Subject: [linus:master] [vfs] 681ce86235: filebench.sum_operations/s -7.4%
regression
hi, Yafang Shao,
we captured this filebench regression after this patch is merged into mailine.
we noticed there is difference with original version in
https://lore.kernel.org/all/20240515091727.22034-1-laoar.shao@gmail.com/
but we confirmed there is similar regression by origial version. details as
below [1] FYI.
Hello,
kernel test robot noticed a -7.4% regression of filebench.sum_operations/s on:
commit: 681ce8623567ba7e7333908e9826b77145312dda ("vfs: Delete the associated dentry when deleting a file")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
[still regression on linus/master 2bfcfd584ff5ccc8bb7acde19b42570414bf880b]
testcase: filebench
test machine: 128 threads 2 sockets Intel(R) Xeon(R) Platinum 8358 CPU @ 2.60GHz (Ice Lake) with 128G memory
parameters:
disk: 1HDD
fs: ext4
test: webproxy.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
