Subject: [vfs] 8bb3c61baf: vm-scalability.median -23.7% regression
Greeting,
FYI, we noticed a -23.7% regression of vm-scalability.median due to commit:
commit: 8bb3c61bafa8c1cd222ada602bb94ff23119e738 ("vfs: Convert ramfs, shmem, tmpfs, devtmpfs, rootfs to use the new mount API")
https://kernel.googlesource.com/pub/scm/linux/kernel/git/viro/vfs.git work.mount
in testcase: vm-scalability
on test machine: 88 threads Intel(R) Xeon(R) CPU E5-2699 v4 @ 2.20GHz with 128G memory
with following parameters:
runtime: 300s
size: 16G
test: shm-pread-rand
cpufreq_governor: performance
ucode: 0xb000036
test-description: The motivation behind this suite is to exercise functions and regions of the mm/ of the Linux kernel which are of interest to us.
test-url: https://git.kernel.org/cgit/linux/kernel/git/wfg/vm-scalability.git/
In addition to that, the commit also has significant impact on the following tests:
