LoongArch: Check for AMO instructions in insns_not_supported()
Like llsc instructions, the atomic memory access instructions shouldn't be supported for probing, so check for them in insns_not_supported().

LoongArch: Introduce hardware page table walker
Loongson-3A6000 and newer processors have hardware page table walker (PTW) support. PTW can handle all fastpaths of TLBI/TLBL/TLBS/TLBM exceptions by hardware, software only need to handle slowpaths (page faults). BTW, PTW doesn't append _PAGE_MODIFIED for page table entries, so we change pmd_dirty() and pte_dirty() to also check _PAGE_DIRTY for the "dirty" attribute.

LoongArch: Support dbar with different hints
Traditionally, LoongArch uses "dbar 0" (full completion barrier) for
everything. But the full completion barrier is a performance killer, so
Loongson-3A6000 and newer processors have made finer granularity hints
available:
Bit4: ordering or completion (0: completion, 1: ordering)
Bit3: barrier for previous read (0: true, 1: false)
Bit2: barrier for previous write (0: true, 1: false)
Bit1: barrier for succeeding read (0: true, 1: false)
Bit0: barrier for succeeding write (0: true, 1: false)
Hint 0x700: barrier for "read after read" from the same address, which
is needed by LL-SC loops on old models (dbar 0x700 behaves the same as
nop if such reordering is disabled on new models).
This patch makes use of the various new hints for different kinds of
memory barriers. It brings performance improvements on Loongson-3A6000
series, while not affecting the existing models because all variants are
treated as 'dbar 0' there.
Why override queued_spin_unlock()?

LoongArch: Add vector extensions support
Add LoongArch's vector extensions support, which including 128bit LSX (i.e., Loongson SIMD eXtension) and 256bit LASX (i.e., Loongson Advanced SIMD eXtension). Linux kernel doesn't use vector itself, it only handle exceptions and context save/restore. So it only needs a subset of these instructions: * Vector load/store: vld vst vldx vstx xvld xvst xvldx xvstx * 8bit-elements move: vpickve2gr.b xvpickve2gr.b vinsgr2vr.b xvinsgr2vr.b * 16bit-elements move: vpickve2gr.h xvpickve2gr.h vinsgr2vr.h xvinsgr2vr.h * 32bit-elements move: vpickve2gr.w xvpickve2gr.w vinsgr2vr.w xvinsgr2vr.w * 64bit-elements move: vpickve2gr.d xvpickve2gr.d vinsgr2vr.d xvinsgr2vr.d * Elements permute: vpermi.w vpermi.d xvpermi.w xvpermi.d xvpermi.q Introduce AS_HAS_LSX_EXTENSION and AS_HAS_LASX_EXTENSION to avoid non- vector toolchains complains unsupported instructions.

LoongArch: Add support to clone a time namespace
We can see that "Time namespaces are not supported" on LoongArch: (1) clone3 test # cd tools/testing/selftests/clone3 && make && ./clone3 ... # Time namespaces are not supported ok 18 # SKIP Skipping clone3() with CLONE_NEWTIME # Totals: pass:17 fail:0 xfail:0 xpass:0 skip:1 error:0 (2) timens test # cd tools/testing/selftests/timens && make && ./timens ... 1..0 # SKIP Time namespaces are not supported On LoongArch the current kernel does not support CONFIG_TIME_NS which depends on GENERIC_VDSO_TIME_NS, select GENERIC_VDSO_TIME_NS to enable CONFIG_TIME_NS to build kernel/time/namespace.c. Additionally, it needs to define some arch-dependent functions for the timens, such as __arch_get_timens_vdso_data(), arch_get_vdso_data() and vdso_join_timens(). At the same time, modify the layout of vvar to use one page size for generic vdso data, expand another page size for timens vdso data and assign LOONGARCH_VDSO_DATA_SIZE (maybe exceeds a page size if expand in the future) for loongarch vdso data, at last add the callback function vvar_fault() and modify stack_top().

Makefile: Add loongarch target flag for Clang compilation
The LoongArch kernel is 64-bit and built with the soft-float ABI, hence the loongarch64-linux-gnusf target. (The "libc" part can affect the codegen of libcalls: other arches do not use a bare-metal target, and currently the only fully supported libc on LoongArch is glibc anyway.)

LoongArch: Tweak CFLAGS for Clang compatibility
Now the arch code is mostly ready for LLVM/Clang consumption, it is time to re-organize the CFLAGS a little to actually enable the LLVM build. Namely, all -G0 switches from CFLAGS are removed, and -mexplicit-relocs and -mdirect-extern-access are now wrapped with cc-option (with the related asm/percpu.h definition guarded against toolchain combos that are known to not work). A build with !RELOCATABLE && !MODULE is confirmed working within a QEMU environment; support for the two features are currently blocked on LLVM/Clang, and will come later. Why -G0 can be removed: In GCC, -G stands for "small data threshold", that instructs the compiler to put data smaller than the specified threshold in a dedicated "small data" section (called .sdata on LoongArch and several other arches). However, benefiting from this would require ABI cooperation, which is not the case for LoongArch; and current GCC behave the same whether -G0 (equal to disabling this optimization) is given or not. So, remove -G0 from CFLAGS altogether for one less thing to care about. This also benefits LLVM/Clang compatibility where the -G switch is not supported. Why -mexplicit-relocs can now be conditionally applied without regressions: Originally -mexplicit-relocs is unconditionally added to CFLAGS in case of CONFIG_AS_HAS_EXPLICIT_RELOCS, because not having it (i.e. old GCC + new binutils) would not work: modules will have R_LARCH_ABS_* relocs inside, but given the rarity of such toolchain combo in the wild, it may not be worthwhile to support it, so support for such relocs in modules were not added back when explicit relocs support was upstreamed, and -mexplicit-relocs is unconditionally added to fail the build early. Now that Clang compatibility is desired, given Clang is behaving like -mexplicit-relocs from day one but without support for the CLI flag, we must ensure the flag is not passed in case of Clang. However, explicit compiler flavor checks can be more brittle than feature detection: in this case what actually matters is support for __attribute__((model)) when building modules. Given neither older GCC nor current Clang support this attribute, probing for the attribute support and #error'ing out would allow proper UX without checking for Clang, and also automatically work when Clang support for the attribute is to be added in the future. Why -mdirect-extern-access is now conditionally applied: This is actually a nice-to-have optimization that can reduce GOT accesses, but not having it is harmless either. Because Clang does not support the option currently, but might do so in the future, conditional application via cc-option ensures compatibility with both current and future Clang versions.

LoongArch: Simplify the invtlb wrappers
The invtlb instruction has been supported by upstream LoongArch toolchains from day one, so ditch the raw opcode trickery and just use plain inline asm for it. While at it, also make the invtlb asm statements barriers, for proper modeling of the side effects. The functions are also marked as __always_inline instead of just "inline", because they cannot work at all if not inlined: the op argument will not be compile-time const in that case, thus failing to satisfy the "i" constraint. The signature of the other more specific invtlb wrappers contain unused arguments right now, but these are not removed right away in order for the patch to be focused. In the meantime, assertions are added to ensure no accidental misuse happens before the refactor. (The more specific wrappers cannot re-use the generic invtlb wrapper, because the ISA manual says $zero shall be used in case a particular op does not take the respective argument: re-using the generic wrapper would mean losing control over the register usage.)

LoongArch: Make the CPUCFG&CSR ops simple aliases of compiler built-ins
In addition to less visual clutter, this also makes Clang happy regarding the const-ness of arguments. In the original approach, all Clang gets to see is the incoming arguments whose const-ness cannot be proven without first being inlined; so Clang errors out here while GCC is fine. While at it, tweak several printk format strings because the return type of csr_read64 becomes effectively unsigned long, instead of unsigned long long.

ksmbd: avoid field overflow warning
clang warns about a possible field overflow in a memcpy:
In file included from fs/smb/server/smb_common.c:7:
include/linux/fortify-string.h:583:4: error: call to '__write_overflow_field' declared with 'warning' attribute: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Werror,-Wattribute-warning]
__write_overflow_field(p_size_field, size);
It appears to interpret the "&out[baselen + 4]" as referring to a single
byte of the character array, while the equivalen "out + baselen + 4" is
seen as an offset into the array.
I don't see that kind of warning elsewhere, so just go with the simple
rework.

Merge branch 'expand-stack'
This modifies our user mode stack expansion code to always take the
mmap_lock for writing before modifying the VM layout.
It's actually something we always technically should have done, but
because we didn't strictly need it, we were being lazy ("opportunistic"
sounds so much better, doesn't it?) about things, and had this hack in
place where we would extend the stack vma in-place without doing the
proper locking.
And it worked fine. We just needed to change vm_start (or, in the case
of grow-up stacks, vm_end) and together with some special ad-hoc locking
using the anon_vma lock and the mm->page_table_lock, it all was fairly
straightforward.
That is, it was all fine until Ruihan Li pointed out that now that the
vma layout uses the maple tree code, we *really* don't just change
vm_start and vm_end any more, and the locking really is broken. Oops.
It's not actually all _that_ horrible to fix this once and for all, and
do proper locking, but it's a bit painful. We have basically three
different cases of stack expansion, and they all work just a bit
differently:
- the common and obvious case is the page fault handling. It's actually
fairly simple and straightforward, except for the fact that we have
something like 24 different versions of it, and you end up in a maze
of twisty little passages, all alike.
- the simplest case is the execve() code that creates a new stack.
There are no real locking concerns because it's all in a private new
VM that hasn't been exposed to anybody, but lockdep still can end up
unhappy if you get it wrong.
- and finally, we have GUP and page pinning, which shouldn't really be
expanding the stack in the first place, but in addition to execve()
we also use it for ptrace(). And debuggers do want to possibly access
memory under the stack pointer and thus need to be able to expand the
stack as a special case.
None of these cases are exactly complicated, but the page fault case in
particular is just repeated slightly differently many many times. And
ia64 in particular has a fairly complicated situation where you can have
both a regular grow-down stack _and_ a special grow-up stack for the
register backing store.
So to make this slightly more manageable, the bulk of this series is to
first create a helper function for the most common page fault case, and
convert all the straightforward architectures to it.
Thus the new 'lock_mm_and_find_vma()' helper function, which ends up
being used by x86, arm, powerpc, mips, riscv, alpha, arc, csky, hexagon,
loongarch, nios2, sh, sparc32, and xtensa. So we not only convert more
than half the architectures, we now have more shared code and avoid some
of those twisty little passages.
And largely due to this common helper function, the full diffstat of
this series ends up deleting more lines than it adds.
That still leaves eight architectures (ia64, m68k, microblaze, openrisc,
parisc, s390, sparc64 and um) that end up doing 'expand_stack()'
manually because they are doing something slightly different from the
normal pattern. Along with the couple of special cases in execve() and
GUP.
So there's a couple of patches that first create 'locked' helper
versions of the stack expansion functions, so that there's a obvious
path forward in the conversion. The execve() case is then actually
pretty simple, and is a nice cleanup from our old "grow-up stackls are
special, because at execve time even they grow down".
The #ifdef CONFIG_STACK_GROWSUP in that code just goes away, because
it's just more straightforward to write out the stack expansion there
manually, instead od having get_user_pages_remote() do it for us in some
situations but not others and have to worry about locking rules for GUP.
And the final step is then to just convert the remaining odd cases to a
new world order where 'expand_stack()' is called with the mmap_lock held
for reading, but where it might drop it and upgrade it to a write, only
to return with it held for reading (in the success case) or with it
completely dropped (in the failure case).
In the process, we remove all the stack expansion from GUP (where
dropping the lock wouldn't be ok without special rules anyway), and add
it in manually to __access_remote_vm() for ptrace().
Thanks to Adrian Glaubitz and Frank Scheiner who tested the ia64 cases.
Everything else here felt pretty straightforward, but the ia64 rules for
stack expansion are really quite odd and very different from everything
else. Also thanks to Vegard Nossum who caught me getting one of those
odd conditions entirely the wrong way around.
Anyway, I think I want to actually move all the stack expansion code to
a whole new file of its own, rather than have it split up between
mm/mmap.c and mm/memory.c, but since this will have to be backported to
the initial maple tree vma introduction anyway, I tried to keep the
patches _fairly_ minimal.
Also, while I don't think it's valid to expand the stack from GUP, the
final patch in here is a "warn if some crazy GUP user wants to try to
expand the stack" patch. That one will be reverted before the final
release, but it's left to catch any odd cases during the merge window
and release candidates.

Networking changes for 6.5.
Core
----
- Rework the sendpage & splice implementations. Instead of feeding
data into sockets page by page extend sendmsg handlers to support
taking a reference on the data, controlled by a new flag called
MSG_SPLICE_PAGES. Rework the handling of unexpected-end-of-file
to invoke an additional callback instead of trying to predict what
the right combination of MORE/NOTLAST flags is.
Remove the MSG_SENDPAGE_NOTLAST flag completely.
- Implement SCM_PIDFD, a new type of CMSG type analogous to
SCM_CREDENTIALS, but it contains pidfd instead of plain pid.
- Enable socket busy polling with CONFIG_RT.
- Improve reliability and efficiency of reporting for ref_tracker.
- Auto-generate a user space C library for various Netlink families.
Protocols
---------
- Allow TCP to shrink the advertised window when necessary, prevent
sk_rcvbuf auto-tuning from growing the window all the way up to
tcp_rmem[2].
- Use per-VMA locking for "page-flipping" TCP receive zerocopy.
- Prepare TCP for device-to-device data transfers, by making sure
that payloads are always attached to skbs as page frags.
- Make the backoff time for the first N TCP SYN retransmissions
linear. Exponential backoff is unnecessarily conservative.
- Create a new MPTCP getsockopt to retrieve all info (MPTCP_FULL_INFO).
- Avoid waking up applications using TLS sockets until we have
a full record.
- Allow using kernel memory for protocol ioctl callbacks, paving
the way to issuing ioctls over io_uring.
- Add nolocalbypass option to VxLAN, forcing packets to be fully
encapsulated even if they are destined for a local IP address.
- Make TCPv4 use consistent hash in TIME_WAIT and SYN_RECV. Ensure
in-kernel ECMP implementation (e.g. Open vSwitch) select the same
link for all packets. Support L4 symmetric hashing in Open vSwitch.
- PPPoE: make number of hash bits configurable.
- Allow DNS to be overwritten by DHCPACK in the in-kernel DHCP client
(ipconfig).
- Add layer 2 miss indication and filtering, allowing higher layers
(e.g. ACL filters) to make forwarding decisions based on whether
packet matched forwarding state in lower devices (bridge).
- Support matching on Connectivity Fault Management (CFM) packets.
- Hide the "link becomes ready" IPv6 messages by demoting their
printk level to debug.
- HSR: don't enable promiscuous mode if device offloads the proto.
- Support active scanning in IEEE 802.15.4.
- Continue work on Multi-Link Operation for WiFi 7.
BPF
---
- Add precision propagation for subprogs and callbacks. This allows
maintaining verification efficiency when subprograms are used,
or in fact passing the verifier at all for complex programs,
especially those using open-coded iterators.
- Improve BPF's {g,s}setsockopt() length handling. Previously BPF
assumed the length is always equal to the amount of written data.
But some protos allow passing a NULL buffer to discover what
the output buffer *should* be, without writing anything.
- Accept dynptr memory as memory arguments passed to helpers.
- Add routing table ID to bpf_fib_lookup BPF helper.
- Support O_PATH FDs in BPF_OBJ_PIN and BPF_OBJ_GET commands.
- Drop bpf_capable() check in BPF_MAP_FREEZE command (used to mark
maps as read-only).
- Show target_{obj,btf}_id in tracing link fdinfo.
- Addition of several new kfuncs (most of the names are self-explanatory):
- Add a set of new dynptr kfuncs: bpf_dynptr_adjust(),
bpf_dynptr_is_null(), bpf_dynptr_is_rdonly(), bpf_dynptr_size()
and bpf_dynptr_clone().
- bpf_task_under_cgroup()
- bpf_sock_destroy() - force closing sockets
- bpf_cpumask_first_and(), rework bpf_cpumask_any*() kfuncs
Netfilter
---------
- Relax set/map validation checks in nf_tables. Allow checking
presence of an entry in a map without using the value.
- Increase ip_vs_conn_tab_bits range for 64BIT builds.
- Allow updating size of a set.
- Improve NAT tuple selection when connection is closing.
Driver API

Merge tag 'net-next-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking changes from Jakub Kicinski:
"WiFi 7 and sendpage changes are the biggest pieces of work for this
release. The latter will definitely require fixes but I think that we
got it to a reasonable point.
Core:
- Rework the sendpage & splice implementations
Instead of feeding data into sockets page by page extend sendmsg
handlers to support taking a reference on the data, controlled by a
new flag called MSG_SPLICE_PAGES
Rework the handling of unexpected-end-of-file to invoke an
additional callback instead of trying to predict what the right
combination of MORE/NOTLAST flags is
Remove the MSG_SENDPAGE_NOTLAST flag completely
- Implement SCM_PIDFD, a new type of CMSG type analogous to
SCM_CREDENTIALS, but it contains pidfd instead of plain pid
- Enable socket busy polling with CONFIG_RT
- Improve reliability and efficiency of reporting for ref_tracker
- Auto-generate a user space C library for various Netlink families
Protocols:
- Allow TCP to shrink the advertised window when necessary, prevent
sk_rcvbuf auto-tuning from growing the window all the way up to
tcp_rmem[2]
- Use per-VMA locking for "page-flipping" TCP receive zerocopy
- Prepare TCP for device-to-device data transfers, by making sure
that payloads are always attached to skbs as page frags
- Make the backoff time for the first N TCP SYN retransmissions
linear. Exponential backoff is unnecessarily conservative
- Create a new MPTCP getsockopt to retrieve all info
(MPTCP_FULL_INFO)
- Avoid waking up applications using TLS sockets until we have a full
record
- Allow using kernel memory for protocol ioctl callbacks, paving the
way to issuing ioctls over io_uring
- Add nolocalbypass option to VxLAN, forcing packets to be fully
encapsulated even if they are destined for a local IP address
- Make TCPv4 use consistent hash in TIME_WAIT and SYN_RECV. Ensure
in-kernel ECMP implementation (e.g. Open vSwitch) select the same
link for all packets. Support L4 symmetric hashing in Open vSwitch
- PPPoE: make number of hash bits configurable
- Allow DNS to be overwritten by DHCPACK in the in-kernel DHCP client
(ipconfig)
- Add layer 2 miss indication and filtering, allowing higher layers
(e.g. ACL filters) to make forwarding decisions based on whether
packet matched forwarding state in lower devices (bridge)
- Support matching on Connectivity Fault Management (CFM) packets
- Hide the "link becomes ready" IPv6 messages by demoting their
printk level to debug
- HSR: don't enable promiscuous mode if device offloads the proto
- Support active scanning in IEEE 802.15.4
- Continue work on Multi-Link Operation for WiFi 7
BPF:
- Add precision propagation for subprogs and callbacks. This allows
maintaining verification efficiency when subprograms are used, or
in fact passing the verifier at all for complex programs,
especially those using open-coded iterators
- Improve BPF's {g,s}setsockopt() length handling. Previously BPF
assumed the length is always equal to the amount of written data.
But some protos allow passing a NULL buffer to discover what the
output buffer *should* be, without writing anything
- Accept dynptr memory as memory arguments passed to helpers
- Add routing table ID to bpf_fib_lookup BPF helper
- Support O_PATH FDs in BPF_OBJ_PIN and BPF_OBJ_GET commands
- Drop bpf_capable() check in BPF_MAP_FREEZE command (used to mark
maps as read-only)
- Show target_{obj,btf}_id in tracing link fdinfo
- Addition of several new kfuncs (most of the names are
self-explanatory):
- Add a set of new dynptr kfuncs: bpf_dynptr_adjust(),
bpf_dynptr_is_null(), bpf_dynptr_is_rdonly(), bpf_dynptr_size()
and bpf_dynptr_clone().
- bpf_task_under_cgroup()
- bpf_sock_destroy() - force closing sockets
- bpf_cpumask_first_and(), rework bpf_cpumask_any*() kfuncs
Netfilter:
- Relax set/map validation checks in nf_tables. Allow checking
presence of an entry in a map without using the value
- Increase ip_vs_conn_tab_bits range for 64BIT builds
- Allow updating size of a set
- Improve NAT tuple selection when connection is closing
Driver API:
- Integrate netdev with LED subsystem, to allow configuring HW
"offloaded" blinking of LEDs based on link state and activity
(i.e. packets coming in and out)
- Support configuring rate selection pins of SFP modules
- Factor Clause 73 auto-negotiation code out of the drivers, provide

v6.5-rc1-sysctl-next
The changes queued up for v6.5-rc1 for sysctl are in line with prior efforts to stop usage of deprecated routines which incur recursion and also make it hard to remove the empty array element in each sysctl array declaration. The most difficult user to modify was parport which required a bit of re-thinking of how to declare shared sysctls there, Joel Granados has stepped up to the plate to do most of this work and eventual removal of register_sysctl_table(). That work ended up saving us about 1465 bytes according to bloat-o-meter. Since we gained a few bloat-o-meter karma points I moved two rather small sysctl arrays from kernel/sysctl.c leaving us only two more sysctl arrays to move left. Most changes have been tested on linux-next for about a month. The last straggler patches are a minor parport fix, changes to the sysctl kernel selftest so to verify correctness and prevent regressions for the future change he made to provide an alternative solution for the special sysctl mount point target which was using the now deprecated sysctl child element. This is all prep work to now finally be able to remove the empty array element in all sysctl declarations / registrations which is expected to save us a bit of bytes all over the kernel. That work will be tested early after v6.5-rc1 is out. -----BEGIN PGP SIGNATURE----- iQJGBAABCgAwFiEENnNq2KuOejlQLZofziMdCjCSiKcFAmSceh0SHG1jZ3JvZkBr ZXJuZWwub3JnAAoJEM4jHQowkoinBFQQAK9WdpcU8ODoDzoSls4jsCQpZUCfZ+ED pbCgQqUqu9VPs6bnJ+aXVa6Fh3uCr6+TIfNFM55qI/Sbo2issZ7bm0nvKmGgc6/m giqDP7btvHqiAsEootci8DVdbBXKkdH4dx3pSwleyN8pdinewH0hrKImaPpahyo6 1mB1du0iI89yjsZmheHVVSyfXXYAnP0PqRVy5Y+qxY7yYlIegQ5uAZmwRE62lfTf TuiV7OFuDZ2DBYOmqIhfGKGRnfOL5ZVF3iHCrfUpX3p+fEFzDmwvm3vr73PTSrFw /aRRLa/hOWr5ilw1bvnMcazgQzFEOlQb3DMhBKH7gLl3XHVrM+TaaqYHjUia1+6Y e2axz/duA2q9uLMW81daRApvHMCgy0exkpC7prfOxF5bgTe4TjA7ZWvGpqG1kPKT PPSxw80XvG5hLZm4tB0ZWJ5rOfFpiUGGneSeRQwyuClBt73SIO+F03jyGpt83slU jFE50ac14Zwh1oxpCQtYoR1+bXWdq1QwM5vQBNEuaoTSnJfVjrXqBz/BnqJChtjr m1vA27+4/dfki2P3gVWF1lGx43ir3uJvqk+BjWXm2CDDJqpRi3N0qcUwZwLuqAAz /LEgFqK61bpHi/C8c2NWAxIoeWRU4NUOaoiKmZwyt0sKAWU1Yzg70xssYeg7VYqZ 3pvFNVBqkV+F =sXUU -----END PGP SIGNATURE----- Merge tag 'v6.5-rc1-sysctl-next' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux Pull sysctl updates from Luis Chamberlain: "The changes for sysctl are in line with prior efforts to stop usage of deprecated routines which incur recursion and also make it hard to remove the empty array element in each sysctl array declaration.

v6.5-rc1-modules-next
The changes queued up for v6.5-rc1 for modules are pretty tame, mostly code removal of moving of code. Only two minor functional changes are made, the only one which stands out is Sebastian Andrzej Siewior's simplification of module reference counting by removing preempt_disable() and that has been tested on linux-next for well over a month without no regressions.

modules: catch concurrent module loads, treat them as idempotent

thousands) of redundant duplicate modules in parallel.

nvme: improved uring polling
Drivers can poll requests directly, so use that. We just need to ensure the driver's request was allocated from a polled hctx, so a special driver flag is added to struct io_uring_cmd. The allows unshared and multipath namespaces to use the same polling callback, and multipath is guaranteed to get the same queue as the command was submitted on. Previously multipath polling might check a different path and poll the wrong info. The other bonus is we don't need a bio payload in order to poll, allowing commands like 'flush' and 'write zeroes' to be submitted on the same high priority queue as read and write commands. Finally, using the request based polling skips the unnecessary bio overhead.

block: add request polling helper
Provide a direct request polling will for drivers. The interface does not require a bio, and can skip the overhead associated with polling those. The biggest gain from skipping the relatively expensive xarray lookup unnecessary when you already have the request. With this, the simple rq/qc conversion functions have only one caller each, so open code this and remove the helpers.

smb: client: fix shared DFS root mounts with different prefixes
When having two DFS root mounts that are connected to same namespace,
same mount options but different prefix paths, we can't really use the
shared @server->origin_fullpath when chasing DFS links in them.
Move the origin_fullpath field to cifs_tcon structure so when having
shared DFS root mounts with different prefix paths, and we need to
chase any DFS links, dfs_get_automount_devname() will pick up the
correct full path out of the @tcon that will be used for the new
mount.
Before patch
mount.cifs //dom/dfs/dir /mnt/1 -o ...
mount.cifs //dom/dfs /mnt/2 -o ...
# shared server, ses, tcon
# server: origin_fullpath=//dom/dfs/dir
# @server->origin_fullpath + '/dir/link1'
$ ls /mnt/2/dir/link1
ls: cannot open directory '/mnt/2/dir/link1': No such file or directory
After patch
mount.cifs //dom/dfs/dir /mnt/1 -o ...
mount.cifs //dom/dfs /mnt/2 -o ...
# shared server & ses
# tcon_1: origin_fullpath=//dom/dfs/dir
# tcon_2: origin_fullpath=//dom/dfs
# @tcon_2->origin_fullpath + '/dir/link1'
$ ls /mnt/2/dir/link1

spi: Updates for v6.5
One small core feature this time around but mostly driver improvements
and additions for SPI:
- Add support for controlling the idle state of MOSI, some systems can
support this and depending on the system integration may need it to
avoid glitching in some situations.
- Support for polling mode in the S3C64xx driver and DMA on the
Qualcomm QSPI driver.
- Support for several Allwinner SoCs, AMD Pensando Elba, Intel Mount
Evans, Renesas RZ/V2M, and ST STM32H7.

the core but otherwise everything is updates to drivers, mostly the
addition of new ones.
There's also a bunch of changes pulled in from the MFD subsystem as
dependencies, Rockchip and TI core MFD code that the regulator drivers
depend on.
I've also yet again managed to put a SPI commit in the regulator tree, I

regmap: Updates for v6.5
Another busy release for regmap with the second half fo the maple tree
register cache implementation, there's some smaller optimisations that
could be done but this should now be able to replace the rbtree cache
for most devices.
We also had a followup from Aidan MacDonald's refactoring of some of the
regmap-irq interfaces, the conversion is complete so the old interfaces
are removed. This means that even with the new features for the maple
tree cache we'd have a nice negative diffstat were it not for the
addition of a bunch more KUnit coverage.
There's one GPIO patch in here, it was a dependency for a cleanup of an
API in the regmap-irq code for which the gpio-104-dio-48e driver was the
only user.
Highlights:
- The maple tree cache can now load in default values more efficiently,
and is capabale of syncing multiple registers in a single write
during cache sync.
- More KUnit coverage, including some coverage for raw I/O and a dummy
RAM backed cache to support it.
- Removal of several old interfaces in regmap-irq now all the users
have been modernised.

io_uring: flush offloaded and delayed task_work on exit
io_uring offloads task_work for cancelation purposes when the task is exiting. This is conceptually fine, but we should be nicer and actually wait for that work to complete before returning. Add an argument to io_fallback_tw() telling it to flush the deferred work when it's all queued up, and have it flush a ctx behind whenever the ctx changes.

smb: client: fix parsing of source mount option
Handle trailing and leading separators when parsing UNC and prefix paths in smb3_parse_devname(). Then, store the sanitised paths in smb3_fs_context::source. This fixes the following cases $ mount //srv/share// /mnt/1 -o ... $ cat /mnt/1/d0/f0 cat: /mnt/1/d0/f0: Invalid argument The -EINVAL was returned because the client sent SMB2_CREATE "\\d0\f0" rather than SMB2_CREATE "\d0\f0". $ mount //srv//share /mnt/1 -o ... mount: Invalid argument The -EINVAL was returned correctly although the client only realised it after sending a couple of bad requests rather than bailing out earlier when parsing mount options.

smb: client: fix broken file attrs with nodfs mounts
*_get_inode_info() functions expect -EREMOTE when query path info
calls find a DFS link, regardless whether !CONFIG_CIFS_DFS_UPCALL or
'nodfs' mount option. Otherwise, those files will miss the fake DFS
file attributes.
Before patch
