hi, Jeff Layton,
we reported a (dramatic) performance regression for this commit
([linux-next:master] [filelock] b6be371400: stress-ng.lockf.ops_per_sec -100.0% regression)
now we also observed it could cause some func failure. FYI.
Hello,
kernel test robot noticed "ltp.fcntl17_64.fail" on:
commit: b6be3714005c3933886be71011f19119e219e77c ("filelock: convert __locks_insert_block, conflict and deadlock checks to use file_lock_core")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
[test failed on linux-next/master ae00c445390b349e070a64dc62f08aa878db7248]
in testcase: ltp
version: ltp-x86_64-14c1f76-1_20240210
with following parameters:
disk: 1HDD
fs: ext4
test: syscalls-03/fcntl17_64
compiler: gcc-12
test machine: 4 threads 1 sockets Intel(R) Core(TM) i3-3220 CPU @ 3.30GHz (Ivy Bridge) with 8G memory
(please refer to attached dmesg/kmsg for entire log/backtrace)
If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags
