[linux-next:master] [fs] d91ea8195e: stress-ng.ring-pipe.ops_per_sec -5.1% regression (stress-ng.ring-pipe.pipe_read+write_calls_per_sec 7.3% improvement)

Hello,
kernel test robot noticed a -5.1% regression of stress-ng.ring-pipe.ops_per_sec
(but also a 7.3% improvement of stress-ng.ring-pipe.pipe_read+write_calls_per_sec
in "miscellaneous metrics" part of the same test) on:
commit: d91ea8195ed416365007d83d2967985dc6d8f882 ("fs: port files to file_ref")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
testcase: stress-ng
config: x86_64-rhel-8.3
compiler: gcc-12
test machine: 224 threads 2 sockets Intel(R) Xeon(R) Platinum 8480CTDX (Sapphire Rapids) with 256G memory
parameters:
nr_threads: 100%
testtime: 60s
test: ring-pipe
cpufreq_governor: performance
In addition to that, the commit also has significant impact on the following tests:
+------------------+-------------------------------------------------------------------------------------------+
| testcase: change | stress-ng: stress-ng.io-uring.ops_per_sec 27.5% improvement |
| test machine | 256 threads 2 sockets GENUINE INTEL(R) XEON(R) (Sierra Forest) with 128G memory |
| test parameters | cpufreq_governor=performance |
| | nr_threads=100% |
| | test=io-uring |
| | testtime=60s |
+------------------+-------------------------------------------------------------------------------------------+
at the same time, we also observed
"dmesg.WARNING:at_fs/file.c:#__file_ref_put"
"dmesg.WARNING:at_fs/open.c:#filp_flush"
"RIP:aa_file_perm"
then kernel crash issues for stress-ng getdent tests as below part [1]
similar to what we reported in
https://lore.kernel.org/all/202410151043.5d224a27-oliver.sang@intel.com/
Details are as below:
