Subject: Re: [PATCH] perf: Remove setting of page->index and ->mapping
Hello,
from commit message, it seems just some useless setting have been removed.
but quite some performance regression bisect by our bot finally point to this
change (already removed some not so significant changes to avoid this report
mail is too long).
we don't have enough knowledge to explain these, so just report FYI.
if you have any suggestion for our tests or need us run more tests, please
just let us know. thanks a lot!
kernel test robot noticed a -28.3% regression of stress-ng.dirmany.files_removed_per_sec on:
