Subject: [lkp] [dcache_{readdir,dir_lseek}() users] 4e82901cd6:
reaim.jobs_per_min -49.1% regression
FYI, we noticed reaim.jobs_per_min -49.1% regression due to commit:
commit 4e82901cd6d1af21ae232ae835c36d8230c809e8 ("dcache_{readdir,dir_lseek}() users: switch to ->iterate_shared")
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
in testcase: reaim
on test machine: lkp-hsx04: 144 threads Brickland Haswell-EX with 512G memory
with following parameters: cpufreq_governor=performance/iterations=4/nr_task=1600%/test=fserver
Details are as below:
