Subject: mm/damon/core: fix wrong comment of damon_call() return timing
Date: Sun, 26 Oct 2025 11:22:06 -0700

Patch series "mm/damon: misc documentation fixups".

First three patches fix up issues in the documents, including wrong
explanation of a behavior, wrong link, and a contextual typo.  Following
five patches update documents for not yet documented features and
behaviors.


This patch (of 8):

damon_call() works asynchronously and synchronously for repeat and
non-repeat mode requests, respectively.  The comment about the behavior is
wrong, though.  Fix it.

The wrong comment was introduced together with the repeat mode, by commit
43df7676e550 ("mm/damon/core: introduce repeat mode damon_call()").
