Hello,
kernel test robot noticed a -22.9% regression of stress-ng.pipeherd.ops_per_sec on:
commit: cc03a5d65a4032f8c53940927343c1795f2d2c53 ("fs/pipe: remove unnecessary spinlock from pipe_write()")
https://git.kernel.org/cgit/linux/kernel/git/vfs/vfs.git vfs.misc.backing_file
testcase: stress-ng
test machine: 64 threads 2 sockets Intel(R) Xeon(R) Gold 6346 CPU @ 3.10GHz (Ice Lake) with 256G memory
parameters:
nr_threads: 10%
disk: 1HDD
testtime: 60s
fs: ext4
class: os
test: pipeherd
cpufreq_governor: performance
In addition to that, the commit also has significant impact on the following tests:
