Subject: [vfs] 27eb9d500d: vm-scalability.median -19.4% regression
Greeting,
FYI, we noticed a -19.4% regression of vm-scalability.median due to commit:
commit: 27eb9d500d71d93e2b2f55c226bc1cc4ba53e9b0 ("vfs: Convert ramfs, shmem, tmpfs, devtmpfs, rootfs to use the new mount API")
https://git.kernel.org/cgit/linux/kernel/git/dhowells/linux-fs.git mount-api-viro
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
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:
