Subject: Revert "mm/compaction: fix set skip in fast_find_migrateblock"
|
|
||||||
|
|
||||||
commit 95e7a450b8190673675836bfef236262ceff084a upstream.
|
|
||||||
|
|
||||||
This reverts commit 7efc3b7261030da79001c00d92bc3392fd6c664c.
|
|
||||||
|
|
||||||
We have got openSUSE reports (Link 1) for 6.1 kernel with khugepaged
|
|
||||||
stalling CPU for long periods of time. Investigation of tracepoint data
|
|
||||||
shows that compaction is stuck in repeating fast_find_migrateblock()
|
|
||||||
based migrate page isolation, and then fails to migrate all isolated
|
|
||||||
pages.
|
|
||||||
|
|
||||||
Commit 7efc3b726103 ("mm/compaction: fix set skip in fast_find_migrateblock")
|
|
||||||
was suspected as it was merged in 6.1 and in theory can indeed remove a
|
|
||||||
termination condition for fast_find_migrateblock() under certain
|
|
||||||
conditions, as it removes a place that always marks a scanned pageblock
|
|
||||||
from being re-scanned. There are other such places, but those can be
|
|
||||||
skipped under certain conditions, which seems to match the tracepoint
|
|
||||||
data.
|
|
||||||
|
|
||||||
Testing of revert also appears to have resolved the issue, thus revert
|
|
||||||
the commit until a more robust solution for the original problem is
|
|
||||||
developed.
|
|
||||||
|
|
||||||
It's also likely this will fix qemu stalls with 6.1 kernel reported in
|
|
||||||
Link 2, but that is not yet confirmed.
