Thanks a lot for taking the time and providing all the details. Please
find an updated version below, which should not exhibit that warning.

Subject: [RFC PATCH v1] perf: Paper over the hw.target problems
First, we have a race between perf_event_release_kernel() and
perf_free_event(), which happens when parent's event is released while the
child's fork fails (because of a fatal signal, for example), that looks
like this:
cpu X cpu Y
----- -----
copy_process() error path
perf_release(parent) +->perf_event_free_task()
+-> lock(child_ctx->mutex) | |
+-> remove_from_context(child) | |
+-> unlock(child_ctx->mutex) | |
| | +-> lock(child_ctx->mutex)
| | +-> unlock(child_ctx->mutex)
| +-> free_task(child_task)
+-> put_task_struct(child_task)
Technically, we're still holding a reference to the task via
parent->hw.target, that's not stopping free_task(), so we end up poking at
free'd memory, as is pointed out by KASAN in the syzkaller report (see Link
below). The straightforward fix is to drop the hw.target reference while
the task is still around.
Therein lies the second problem: the users of hw.target (uprobe) assume
that it's around at ->destroy() callback time, where they use it for
context. So, in order to not break the uprobe teardown and avoid leaking
stuff, we need to call ->destroy() at the same time.
This patch fixes the race and the subsequent fallout by doing both these
things at remove_from_context time.

[x86, retpolines] ce02ef06fc: will-it-scale.per_thread_ops 3.1% improvement
by kernel test robot
Greeting,
FYI, we noticed a 3.1% improvement of will-it-scale.per_thread_ops due to commit:
commit: ce02ef06fcf7a399a6276adb83f37373d10cbbe1 ("x86, retpolines: Raise limit for generating indirect calls from switch-case")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: will-it-scale
on test machine: 88 threads Intel(R) Xeon(R) CPU E5-2699 v4 @ 2.20GHz with 64G memory
with following parameters:
nr_task: 100%
mode: thread
test: futex3
cpufreq_governor: performance
ucode: 0xb00002e
test-description: Will It Scale takes a testcase and runs it from 1 through to n parallel copies to see if the testcase will scale. It builds both a process and threads based test in order to see any differences between the two.
test-url: https://github.com/antonblanchard/will-it-scale
In addition to that, the commit also has significant impact on the following tests:

[net] a410c2b2f6: WARNING:at_kernel/locking/lockdep.c:#lock_release
by kernel test robot
FYI, we noticed the following commit (built with gcc-5):
commit: a410c2b2f6fb75626ec604371f0765d9438c7d37 ("net: devlink: Don't take devlink_mutex for devlink_compat_*")
https://github.com/jpirko/linux_mlxsw jiri_devel_devlink
in testcase: locktorture
with following parameters:
runtime: 300s
test: default
test-description: This torture test consists of creating a number of kernel threads which acquire the lock and hold it for specific amount of time, thus simulating different critical region behaviors.
test-url: https://www.kernel.org/doc/Documentation/locking/locktorture.txt
on test machine: qemu-system-x86_64 -enable-kvm -cpu SandyBridge -smp 2 -m 2G

Yes, this is a correctness issue that we discovered while tracking
down user data loss issue after a crash of the NFS server, so this is
a change we have to keep. When the NFS folks added the
commit_metadata() hook, they didn't realize that the fallback path in
nfsd/vfs.c using sync_inode_metadata() doesn't work on all file
systems --- and in particular doesn't work for ext3 and ext4 because
of how we do journalling.
It only applies to NFS serving, not local ext4 use cases, so most ext4
users won't be impacted on it; only those who export those file
systems using NFS.
I do have some plans on how to claw back the performance hit. The
good news is that it won't require an on-disk format change; the bad
news is that it's a non-trivial change to how journalling works, and
it's not something we can backport to the stable kernel series. It's
something we're going to have to leave to a distribution who is
willing to do a lot of careful regression testing, once the change is
available, maybe in 3 months or so.
- Ted
P.S. I *believe* all other file systems should be OK, and I didn't
want to impose a performance tax on all other file systems (such as
btrfs), so I fixed it in an ext4-specific way. The more
general/conservative change would be to fall back to using fsync in
nfs/vfs.c:commit_metadata() unless the file system specifically set a
superblock flag indicating that using sync_inode_metadata is safe.
OTOH we lived with this flaw in ext3/ext4 for *years* without anyone
noticing or complaining, so....

[btrfs] 44fe89de7d: aim7.jobs-per-min -15.1% regression
by kernel test robot
Greeting,
FYI, we noticed a -15.1% regression of aim7.jobs-per-min due to commit:
commit: 44fe89de7d5157a4f31f13d94802c7619e23f462 ("btrfs: Do mandatory tree block check before submitting bio")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
in testcase: aim7
on test machine: 72 threads Intel(R) Xeon(R) Gold 6139 CPU @ 2.30GHz with 128G memory
with following parameters:
disk: 4BRD_12G
md: RAID0
fs: btrfs
test: sync_disk_rw
load: 20
cpufreq_governor: performance
test-description: AIM7 is a traditional UNIX system level benchmark suite which is used to test and measure the performance of multiuser system.
test-url: https://sourceforge.net/projects/aimbench/files/aim-suite7/
In addition to that, the commit also has significant impact on the following tests:

in testcase: kernel_selftests
with following parameters:
group: kselftests-03
test-description: The kernel contains a set of "self tests" under the tools/testing/selftests/ directory. These are intended to be small unit tests to exercise individual code paths in the kernel.
