mm,kmemleak-test.c: move kmemleak-test.c to samples dir
kmemleak-test.c is just a kmemleak test module, which also can not be used as a built-in kernel module. Thus, i think it may should not be in mm dir, and move the kmemleak-test.c to samples/kmemleak/kmemleak-test.c. Fix the spelling of built-in by the way.

mm/kmemleak: rely on rcu for task stack scanning
kmemleak_scan() currently relies on the big tasklist_lock hammer to stabilize iterating through the tasklist. Instead, this patch proposes simply using rcu along with the rcu-safe for_each_process_thread flavor (without changing scan semantics), which doesn't make use of next_thread/p->thread_group and thus cannot race with exit. Furthermore, any races with fork() and not seeing the new child should be benign as it's not running yet and can also be detected by the next scan. Avoiding the tasklist_lock could prove beneficial for performance considering the scan operation is done periodically. I have seen improvements of 30%-ish when doing similar replacements on very pathological microbenchmarks (ie stressing get/setpriority(2)). However my main motivation is that it's one less user of the global lock, something that Linus has long time wanted to see gone eventually (if ever) even if the traditional fairness issues has been dealt with now with qrwlocks. Of course this is a very long ways ahead. This patch also kills another user of the deprecated tsk->thread_group.

ocfs2: fix potential soft lockup during fstrim
When we discard unused blocks on a mounted ocfs2 filesystem, fstrim handles each block goup with locking/unlocking global bitmap meta-file repeatedly. we should let fstrim thread take a break(if need) between unlock and lock, this will avoid the potential soft lockup problem, and also gives the upper applications more IO opportunities, these applications are not blocked for too long at writing files.

kbuild: doc: describe proper script invocation
During an investigation to fix up the execute bits of scripts in the kernel repository, Andrew Morton and Kees Cook pointed out that the execute bit should not matter, and that build scripts cannot rely on that. Kees could not point to any documentation, though. Masahiro Yamada explained the convention of setting execute bits to make it easier for manual script invocation. Provide some basic documentation how the build shall invoke scripts, such that the execute bits do not matter, and acknowledge that execute bits are useful nonetheless. This serves as reference for further clean-up patches in the future.

export.h: fix section name for CONFIG_TRIM_UNUSED_KSYMS for Clang
When enabling CONFIG_TRIM_UNUSED_KSYMS, the linker will warn about the
orphan sections:
(".discard.ksym") is being placed in '".discard.ksym"'
repeatedly when linking vmlinux. This is because the stringification
operator, `#`, in the preprocessor escapes strings. GCC and Clang differ
in how they treat section names that contain \".
The portable solution is to not use a string literal with the preprocessor
stringification operator.

compiler.h: avoid escaped section names
The stringification operator, `#`, in the preprocessor escapes strings.
For example, `# "foo"` becomes `"\"foo\""`. GCC and Clang differ in how
they treat section names that contain \".
The portable solution is to not use a string literal with the preprocessor
stringification operator.
In this case, since __section unconditionally uses the stringification
operator, we actually want the more verbose
__attribute__((__section__())).

compiler-gcc: improve version error
As Kees suggests, doing so provides developers with two useful pieces of
information:
- The kernel build was attempting to use GCC.
(Maybe they accidentally poked the wrong configs in a CI.)
- They need 4.9 or better.
("Upgrade to what version?" doesn't need to be dug out of documentation,
headers, etc.)

Patch series "set clang minimum version to 10.0.1", v3. Adds a compile time #error to compiler-clang.h setting the effective minimum supported version to clang 10.0.1. A separate patch has already been picked up into the Documentation/ tree also confirming the version. Next are a series of reverts. One for 32b arm is a partial revert. Then Marco suggested fixes to KASAN docs. Finally, improve the warning for GCC too as per Kees. This patch (of 7): During Plumbers 2020, we voted to just support the latest release of Clang for now. Add a compile time check for this. We plan to remove workarounds for older versions now, which will break in subtle and not so subtle ways.

"Two asm wrapper fixes:
- Use XORL instead of XORQ to avoid a REX prefix and save some bytes
in the .fixup section, by Uros Bizjak.
- Replace __force_order dummy variable with a memory clobber to fix
LLVM requiring a definition for former and to prevent memory
accesses from still being cached/reordered, by Arvind Sankar"

GPIO bulk changes for the v5.10 kernel cycle:
Core changes:
- The big core change is the updated (v2) userspace character
device API. This corrects badly designed 64-bit alignment around
the line events. We also add the debounce request feature.
This echoes the often quotes passage from Frederick Brooks
"The mythical man-month" to always throw one away, which we
have seen before in things such as V4L2. So we put in a new
one and deprecate and obsolete the old one.
- All example tools in tools/gpio/* are migrated to the new API
to set a good example. The libgpiod userspace library has been
augmented to use this new API pretty much from day 1.
- Some misc API hardening by using strn* function calls has been
added as well.
- Use the simpler IDA interface for GPIO chip instance enumeration.
- Add device core function for counting string arrays in
device properties.
- Provide a generic library function kfree_strarray() that can
be used throughout the kernel.
Driver enhancements:
- The DesignWare dwapb-gpio driver has been enhanced and now
uses the IRQ handling in the gpiolib core.
- The mockup and aggregator drivers have seen some substantial
code clean-up and now use more of the core kernel
inftrastructure.
- Misc cleanups using dev_err_probe().
- The MXC drivers (Freescale/NXP) can now be built modularized,
which makes modularized GKI Android kernels happy.

Pull GPIO updates from Linus Walleij:
"This time very little driver changes but lots of core changes.
We have some interesting cooperative work for ARM and Intel alike,
making the GPIO subsystem more and more suitable for industrial
systems and the like, in addition to the in-kernel users.
We touch driver core (device properties) and lib/* by adding one
simple string array free function, these are authored by Andy
Shevchenko who is a well known and recognized core helpers maintainers
so this should be fine.
We also see some Android GKI-related modularization in the MXC
drivers.
Core changes:
- The big core change is the updated (v2) userspace character device
API.
This corrects badly designed 64-bit alignment around the line
events. We also add the debounce request feature. This echoes the
often quotes passage from Frederick Brooks "The mythical man-month"
to always throw one away, which we have seen before in things such
as V4L2. So we put in a new one and deprecate and obsolete the old
one.
- All example tools in tools/gpio/* are migrated to the new API to
set a good example. The libgpiod userspace library has been
augmented to use this new API pretty much from day 1.
- Some misc API hardening by using strn* function calls has been
added as well.
- Use the simpler IDA interface for GPIO chip instance enumeration.
- Add device core function for counting string arrays in device
properties.
- Provide a generic library function kfree_strarray() that can be
used throughout the kernel.
Driver enhancements:
- The DesignWare dwapb-gpio driver has been enhanced and now uses the
IRQ handling in the gpiolib core.
- The mockup and aggregator drivers have seen some substantial code
clean-up and now use more of the core kernel inftrastructure.
- Misc cleanups using dev_err_probe().
- The MXC drivers (Freescale/NXP) can now be built modularized, which
makes modularized GKI Android kernels happy"

spi: Updates for v5.10
There's quite a lot of changes for SPI in this release but none in the
core, they're all mostly small driver updates and additions. Some of
the more notable changes include:
- A huge set of cleanups, optimizations and improvements for the
DesignWare driver from Serge Semin finishing up the work started
last release.
- Conversion of the Zynq gqspi driver to spi-mem.
- Support for Baikal T1, Broadcom BCMSTB 7445, and Renesas R8A7742.

Merge tag 'for-5.10-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs updates from David Sterba:
"Mostly core updates with a few user visible bits and fixes.
Hilights:
- fsync performance improvements
- less contention of log mutex (throughput +4%, latency -14%,
dbench with 32 clients)
- skip unnecessary commits for link and rename (throughput +6%,
latency -30%, rename latency -75%, dbench with 16 clients)
- make fast fsync wait only for writeback (throughput +10..40%,
runtime -1..-20%, dbench with 1 to 64 clients on various
file/block sizes)
- direct io is now implemented using the iomap infrastructure, that's
the main part, we still have a workaround that requires an iomap
API update, coming in 5.10
- new sysfs exports:
- information about the exclusive filesystem operation status
(balance, device add/remove/replace, ...)
- supported send stream version
Core:
- use ticket space reservations for data, fair policy using the same
infrastructure as metadata
- preparatory work to switch locking from our custom tree locks to
standard rwsem, now the locking context is propagated to all
callers, actual switch is expected to happen in the next dev cycle
- seed device structures are now using list API
- extent tracepoints print proper tree id
- unified range checks for extent buffer helpers
- send: avoid using temporary buffer for copying data
- remove unnecessary RCU protection from space infos
- remove unused readpage callback for metadata, enabling several
cleanups
- replace indirect function calls for end io hooks and remove
extent_io_ops completely
Fixes:
- more lockdep warning fixes
- fix qgroup reservation for delayed inode and an occasional
reservation leak for preallocated files
- fix device replace of a seed device
- fix metadata reservation for fallocate that leads to transaction
aborts
- reschedule if necessary when logging directory items or when
cloning lots of extents
- tree-checker: fix false alert caused by legacy btrfs root item
- send: fix rename/link conflicts for orphanized inodes
- properly initialize device stats for seed devices
- skip devices without magic signature when mounting
Other:
- error handling improvements, BUG_ONs replaced by proper handling,
fuzz fixes
- various function parameter cleanups
- various W=1 cleanups
- error/info messages improved
Mishaps:
- commit

fscrypt updates for 5.10
This release, we rework the implementation of creating new encrypted files in order to fix some deadlocks and prepare for adding fscrypt support to CephFS, which Jeff Layton is working on. We also export a symbol in preparation for the above-mentioned CephFS support and also for ext4/f2fs encrypt+casefold support. Finally, there are a few other small cleanups. As usual, all these patches have been in linux-next with no reported issues, and I've tested them with xfstests. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQSacvsUNc7UX4ntmEPzXCl4vpKOKwUCX4SD7xQcZWJpZ2dlcnNA Z29vZ2xlLmNvbQAKCRDzXCl4vpKOKy/AAP92oOybTcuahmvAtHqZP9jAFPJrbI3r 6QLpMFtWznJoOQEAogaWsavtOIBx9afdOfRNj0zdoBIjpXgyMuzR10Ou2gE= =B/Mj -----END PGP SIGNATURE----- Merge tag 'fscrypt-for-linus' of git://git.kernel.org/pub/scm/fs/fscrypt/fscrypt Pull fscrypt updates from Eric Biggers: "This release, we rework the implementation of creating new encrypted files in order to fix some deadlocks and prepare for adding fscrypt support to CephFS, which Jeff Layton is working on.

x86/uaccess: utilize CONFIG_CC_HAS_ASM_GOTO_OUTPUT
Clang-11 shipped support for outputs to asm goto statments along the fallthrough path. Double up some of the get_user() and related macros to be able to take advantage of this extended GNU C extension. This should help improve the generated code's performance for these accesses.

x86: Make __put_user() generate an out-of-line call
Instead of inlining the stac/mov/clac sequence (which also requires individual exception table entries and several asm instruction alternatives entries), just generate "call __put_user_nocheck_X" for the __put_user() cases, the same way we changed __get_user earlier. Unlike the get_user() case, we didn't have the same nice infrastructure to just generate the call with a single case, so this actually has to change some of the infrastructure in order to do this. But that only cleans up the code further. So now, instead of using a case statement for the sizes, we just do the same thing we've done on the get_user() side for a long time: use the size as an immediate constant to the asm, and generate the asm that way directly. In order to handle the special case of 64-bit data on a 32-bit kernel, I needed to change the calling convention slightly: the data is passed in %eax[:%edx], the pointer in %ecx, and the return value is also returned in %ecx. It used to be returned in %eax, but because of how %eax can now be a double register input, we don't want mix that with a single-register output. The actual low-level asm is easier to handle: we'll just share the code between the checking and non-checking case, with the non-checking case jumping into the middle of the function. That may sound a bit too special, but this code is all very very special anyway, so...

x86: Make __get_user() generate an out-of-line call
Instead of inlining the whole stac/lfence/mov/clac sequence (which also requires individual exception table entries and several asm instruction alternatives entries), just generate "call __get_user_nocheck_X" for the __get_user() cases. We can use all the same infrastructure that we already do for the regular "get_user()", and the end result is simpler source code, and much simpler code generation. It also means that when I introduce asm goto with input for "unsafe_get_user()", there are no nasty interactions with the __get_user() code.

Generally I'm less enthusiastic about "let's use in_compat_syscall() deep in call chain" kind of approach than Christoph seems to be, but in this case it's warranted - that had been an NFS-specific wart, hopefully not to be repeated in any other filesystems (read: any new filesystem introducing non-text mount options will get NAKed even if it doesn't mess the layout up).
