Hello,
kernel test robot noticed a -40.3% regression of filebench.sum_operations/s on:
commit: cbc06310c36f73a5f3b0c6f0d974d60cf66d816b ("xfs: reinstate the old i_version counter as STATX_CHANGE_COOKIE")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
testcase: filebench
test machine: 96 threads 2 sockets Intel(R) Xeon(R) Platinum 8260L CPU @ 2.40GHz (Cascade Lake) with 128G memory
parameters:
disk: 1HDD
fs: xfs
fs2: nfsv4
test: filemicro_rread.f
cpufreq_governor: performance
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
