Subject: mm/damon/core: unset damos->walk_completed after confimed set
Date: Mon, 10 Feb 2025 10:27:34 -0800

Patch series "mm/damon/core: fix wrong and/or useless damos_walk()
behaviors".

damos_walk() can finish working earlier or later than expected, and start
earlier than practical.  First two behaviors are clearly wrong behavior
(doesn't follow the documentation) and all three behaviors are only making
the feature useless.  Fix those.


This patch (of 3):

damos->walk_completed is only set, not unset.  This can cause next
damos_walk() finish earlier than expected.  Unset it after all
walk_completed is confirmed.
