Subject: Re: [PATCH] mm/damon/core: reset watermark wait state on each iteration
Date: Fri, 23 Oct 2026 16:06:38 +0000 [thread overview]
Message-ID: <sashiko-outbox-182938@kernel.org> (raw)
In-Reply-To: <179277129124.2.16132047926074873101.damon-empty-schemes@gmail.com>
> Found while reviewing the DAMON source code that if an online commit
> removes all schemes while kdamond is waiting for watermark activation,
> the scheme loop becomes empty but min_wait_time keeps the previous
> positive value. kdamond then keeps sleeping instead of resuming
> monitoring without schemes.
>
> Initialize min_wait_time and init_wait_time on each loop iteration so
> the wait is calculated from the current schemes and an empty scheme
> list resumes monitoring.
>
> Fixes: 6e74d2bf5a26 ("mm/damon/core: add a new callback for watermarks checks")
