Re: [linus:master] [page cache] 9425c591e0: vm-scalability.throughput -20.0% regression

[Linux regression tracking #adding (Thorsten Leemhuis)]

[I know this is mostly been dealt with already, but due to the immanent
release I'll add this to the tracking to make sure Linus becomes aware
of this]

[TLDR: I'm adding this report to the list of tracked Linux kernel
regressions; the text you find below is based on a few templates
paragraphs you might have encountered already in similar form.
See link in footer if these mails annoy you.]

Thanks for the report. To be sure the issue doesn't fall through the
cracks unnoticed, I'm adding it to regzbot, the Linux kernel regression
tracking bot:

#regzbot ^introduced 9425c591e06a
#regzbot title mm/page cache: performance regression (2 reverts pending)
#regzbot monitor:

#regzbot ignore-activity

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)
