[PATCH 1/3] mm/damon/core: unset damos->walk_completed after confimed set

From: SeongJae Park
Date: Mon Feb 10 2025 - 13:28:04 EST


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.

Fixes: bf0eaba0ff9c ("mm/damon/core: implement damos_walk()")
