perf report: Do not extend sample type of bpf-output event
Currently evsel__new_idx() sets more sample_type bits when it finds a BPF-output event. But it should honor what's recorded in the perf data file rather than blindly sets the bits. Otherwise it could lead to a parse error when it recorded with a modified sample_type.

perf test: Add checking for perf stat CSV output.
Counts expected fields for various commands. No testing added for
summary mode since it is broken.
An example of the summary output is:
summary,263831,,instructions:u,1435072,100.0,0.46,insn per cycle
,,,,,1.37,stalled cycles per insn
This should be:
summary,263831,,instructions:u,1435072,100.0,0.46,insn per cycle
summary,,,,,,1.37,stalled cycles per insn
The output has 7 fields when it should have 8. Additionally, the newline
spacing is wrong, so it was excluded from testing until a fix is made.
Committer testing:
$ perf test "perf stat CSV output"
88: perf stat CSV output linter : Ok
$
$ perf test -v "perf stat CSV output"
Couldn't bump rlimit(MEMLOCK), failures may take place when creating BPF maps, etc
88: perf stat CSV output linter :

perf stat: Add requires_cpu flag for uncore
Uncore events require a CPU i.e. it cannot be -1. The evsel system_wide flag is intended for events that should be on every CPU, which does not make sense for uncore events because uncore events do not map one-to-one with CPUs. These 2 requirements are not exactly the same, so introduce a new flag 'requires_cpu' for the uncore case.

NFSD: Fix possible sleep during nfsd4_release_lockowner()
nfsd4_release_lockowner() holds clp->cl_lock when it calls check_for_locks(). However, check_for_locks() calls nfsd_file_get() / nfsd_file_put() to access the backing inode's flc_posix list, and nfsd_file_put() can sleep if the inode was recently removed. Let's instead rely on the stateowner's reference count to gate whether the release is permitted. This should be a reliable indication of locks-in-use since file lock operations and ->lm_get_owner take appropriate references, which are released appropriately when file locks are removed.

perf build: Fix btf__load_from_kernel_by_id() feature check
The btf__load_from_kernel_by_id() only takes one arg, not two.
Committer notes:
I tested it just with an older libbpf, one where
btf__load_from_kernel_by_id() wasn't introduced yet.
A test with a newer dynamic libbpf would fail because the
btf__load_from_kernel_by_id() is there, but takes just one arg.
Fixes:

scsi: storvsc: Removing Pre Win8 related logic
The latest storvsc code has already removed the support for windows 7 and earlier. There is still some code logic remaining which is there to support pre Windows 8 OS. This patch removes these stale logic. This patch majorly does three things : 1. Removes vmscsi_size_delta and its logic, as the vmscsi_request struct is same for all the OS post windows 8 there is no need of delta. 2. Simplify sense_buffer_size logic, as there is single buffer size for all the post windows 8 OS. 3. Embed the vmscsi_win8_extension structure inside the vmscsi_request, as there is no separate handling required for different OS.

MIPS: RALINK: Define pci_remap_iospace under CONFIG_PCI_DRIVERS_GENERIC
kernel test robot reports a build error used with clang compiler and
mips-randconfig [1]:
ld.lld: error: undefined symbol: pci_remap_iospace
we can see the following configs in the mips-randconfig file:
CONFIG_RALINK=y
CONFIG_SOC_MT7620=y
CONFIG_PCI_DRIVERS_LEGACY=y
CONFIG_PCI=y
CONFIG_RALINK is set, so pci_remap_iospace is defined in the related
arch/mips/include/asm/mach-ralink/spaces.h header file:
#define pci_remap_iospace pci_remap_iospace
CONFIG_PCI is set, so pci_remap_iospace() in drivers/pci/pci.c is not
built due to pci_remap_iospace is defined under CONFIG_RALINK.
#ifndef pci_remap_iospace
int pci_remap_iospace(const struct resource *res, ...)
$ objdump -d drivers/pci/pci.o | grep pci_remap_iospace
00004cc8 <devm_pci_remap_iospace>:
4d18: 10400008 beqz v0,4d3c <devm_pci_remap_iospace+0x74>
4d2c: 1040000c beqz v0,4d60 <devm_pci_remap_iospace+0x98>
4d70: 1000fff3 b 4d40 <devm_pci_remap_iospace+0x78>
In addition, CONFIG_PCI_DRIVERS_GENERIC is not set, so pci_remap_iospace()
in arch/mips/pci/pci-generic.c is not built too.
#ifdef pci_remap_iospace
int pci_remap_iospace(const struct resource *res, ...)
For the above reasons, undefined reference pci_remap_iospace() looks like
reasonable.
Here are simple steps to reproduce used with gcc and defconfig:
cd mips.git
make vocore2_defconfig # set RALINK, SOC_MT7620, PCI_DRIVERS_LEGACY
make menuconfig # set PCI
make
there exists the following build error:
LD vmlinux.o
MODPOST vmlinux.symvers
MODINFO modules.builtin.modinfo
GEN modules.builtin
LD .tmp_vmlinux.kallsyms1
drivers/pci/pci.o: In function `devm_pci_remap_iospace':
pci.c:(.text+0x4d24): undefined reference to `pci_remap_iospace'
Makefile:1158: recipe for target 'vmlinux' failed
make: *** [vmlinux] Error 1
Define pci_remap_iospace under CONFIG_PCI_DRIVERS_GENERIC can fix the build
error, with this patch, no build error remains. This patch is similar with
commit

xfs: Changes for 5.19-rc1
This update includes:
- support for printk message indexing.
- large extent counts to provide support for up to 2^47 data extents and 2^32
attribute extents, allowing us to scale beyond 4 billion data extents
to billions of xattrs per inode.
- conversion of various flags fields to be consistently declared as
unsigned bit fields.
- improvements to realtime extent accounting and converts them to per-cpu
counters to match all the other block and inode accounting.
- reworks core log formatting code to reduce iterations, have a shorter, cleaner
fast path and generally be easier to understand and maintain.
- improvements to rmap btree searches that reduce overhead by up
to 30% resulting in xfs_scrub runtime reductions of 15%.
- improvements to reflink that remove the size limitations in remapping operations
and greatly reduce the size of transaction reservations.
- reworks the minimum log size calculations to allow us to change transaction
reservations without changing the minimum supported log size.
- removal of quota warning support as it has never been used on Linux.
- intent whiteouts to allow us to cancel intents that are completed entirely
in memory rather than having use CPU and disk bandwidth formatting and writing
them into the journal when it is not necessary. This makes rmap, reflink and
extent freeing slightly more efficient, but provides massive improvements
for....
- Logged Attribute Replay feature support. This is a fundamental change to the
way we modify attributes, laying the foundation for future integration of
attribute modifications as part of other atomic transactional operations the
filesystem performs.
- Lots of cleanups and fixes for the logged attribute replay functionality.

Merge tag 'xfs-5.19-for-linus' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull xfs updates from Dave Chinner:
"This is a big update with lots of new code. The summary below them
all, so I'll just touch on teh higlights. The two main new features
are Large Extent Counts and Logged Attribute Replay - these are two
new foundational features that we are building more complex future
features on top of.
For upcoming functionality, we need to be able to store hundreds of
millions of xattrs per inode. The Large Extent Count feature removes
the limits that prevent this scale of xattr storage, and while we were
modifying the on disk extent count format we also increased the number
of data extents we support per inode from 2^32 to 2^47.
We also need to be able to modify xattrs as part of larger atomic
transactions rather than as standalone transactions. The Logged
Attribute Replay feature introduces the infrastructure that allows us
to use intents to record the attribute modifications in the journal
before we start them, hence allowing other atomic transactions to log
attribute modification intents and then defer the actual modification
to later. If we then crash, log recovery then guarantees that the
attribute is replayed in the context of the atomic transaction that
logged the intent.
A significant chunk of the commits in this merge are for the base
attribute replay functionality along with fixes, improvements and
cleanups related to this new functioanlity. Allison deserves a big
round of thanks for her ongoing work to get this functionality into
XFS.
There are also many other smaller changes and improvements, so overall
this is one of the bigger XFS merge requests in some time.
I will be following up next week with another smaller pull request -
we already have another round of fixes and improvements to the logged
attribute replay functionality just about ready to go. They'll soak
and test over the next week, and I'll send a pull request for them
near the end of the merge window.
Summary:
- support for printk message indexing.
- large extent counts to provide support for up to 2^47 data extents
and 2^32 attribute extents, allowing us to scale beyond 4 billion
data extents to billions of xattrs per inode.

sound updates for 5.19-rc1
Not much dramatic changes at this time, but we've received quite
a lot of changes for ASoC, while there are still a few fixes and
quirks for usual HD- and USB-auido. Here are some highlights.
* ASoC:
- Overhaul of endianness specification for data formats, avoiding
needless restrictions due to CODECs
- Initial stages of Intel AVS driver merge
- Introduction of v4 IPC mechanism for SOF
- TDM mode support for AK4613
- Support for Analog Devices ADAU1361, Cirrus Logic CS35L45, Maxim
MAX98396, MediaTek MT8186, NXP i.MX8 micfil and SAI interfaces,
nVidia Tegra186 ASRC, and Texas Instruments TAS2764 and TAS2780
* Others
- A few regression fixes after the USB-audio endpoint management
refactoring
- More enhancements for Cirrus HD-audio codec support (still ongoing)
- Addition of generic serial MIDI driver

RISC-V: Fix the XIP build
A handful of functions unused functions were enabled during XIP builds,
which themselves didn't build correctly. This just disables the
functions entirely.

RISC-V: Split out the XIP fixups into their own file
This was broken by the original refactoring (as the XIP definitions depend on <asm/pgtable.h>) and then more broken by the merge (as I accidentally took the old version). This fixes both breakages, while also pulling this out of <asm/asm.h> to avoid polluting most assembly files with the XIP fixups. Fixes: |

tracing: Reset the function filter after completing trampoline/graph selftest
The direct trampoline and graph coexistence test sets global_ops to
trace only 'trace_selftest_dynamic_test_func', but does not reset it
after the test is completed, resulting in the function filter being set
already after the system starts. Although it can be reset through the
tracefs interface, it is more or less confusing to the user, and we
should reset it to trace all functions after the trampoline/graph test
completes.

tracing: Have event format check not flag %p* on __get_dynamic_array()
The print fmt check against trace events to make sure that the format does
not use pointers that may be freed from the time of the trace to the time
the event is read, gives a false positive on %pISpc when reading data that
was saved in __get_dynamic_array() when it is perfectly fine to do so, as
the data being read is on the ring buffer.
