[lkp-robot] [fs] 62231fd3ed: aim7.jobs-per-min 229.5% improvement
by kernel test robot
Greeting,
FYI, we noticed a 229.5% improvement of aim7.jobs-per-min due to commit:
commit: 62231fd3ed94c9d40b4e58ab14fe173f09e252da ("fs: handle inode->i_version more efficiently")
https://git.kernel.org/cgit/linux/kernel/git/jlayton/linux.git iversion-next
in testcase: aim7
on test machine: 40 threads Intel(R) Xeon(R) CPU E5-2690 v2 @ 3.00GHz with 384G memory
with following parameters:
disk: 4BRD_12G
md: RAID0
fs: xfs
test: disk_cp
load: 3000
cpufreq_governor: performance
test-description: AIM7 is a traditional UNIX system level benchmark suite which is used to test and measure the performance of multiuser system.
test-url: https://sourceforge.net/projects/aimbench/files/aim-suite7/
In addition to that, the commit also has significant impact on the following tests:

x86/cpu_entry_area: Move it out of the fixmap
Put the cpu_entry_area into a separate P4D entry. The fixmap gets too big
and 0-day already hit a case where the fixmap PTEs were cleared by
cleanup_highmap().
Aside of that the fixmap API is a pain as it's all backwards.

Add git repo to automatic lkp tests
by Lorenzo Pieralisi
Hi,
I would like to ask you please to add this repo:
https://git.kernel.org/pub/scm/linux/kernel/git/lpieralisi/pci.git/
to the list of automatically tested trees, actually
it would be great if compile tests can be carried out
every time a branch is pushed in the repo, I think
that's the default.
Thank you very much,
Lorenzo
