Hello,
Here is the third version of my mballoc improvements to avoid spreading
allocations with mb_optimize_scan=1. Since v2 there are only small changes and
fixes found during review and testing. Overall the series looks mostly ready to
go, I just didn't see any comments regarding patch 3 - a fix of metabg handling
in the Orlov allocator which is kind of independent, I've just found it when
reading the code. Also patch 5 needs final review after all the fixes.
Changes since v1:
- reworked data structure for CR 1 scan
- make small closed files use locality group preallocation
- fix metabg handling in the Orlov allocator
Changes since v2:
- whitespace fixes
- fix outdated comment
- fix handling of mb_structs_summary procfs file
- fix bad unlock on error recovery path
unfortunately the real patches doesn't have v3 which leads to confusion.
Yeah, OK, I've updated my scripting for posting patches to include version
in each posted patch :)
Just a note: in case this series cannot be applied for stable (5.15), we
need a second solution to fix the regression there.
My plan is to backport the current series. It is not that invasive so it
should be doable...
This would be great.
Btw i retested this version and i can confirm the procfs crash is fixed.
