Subject: [RFC PATCH 0/2] mm/damon/stat: add kdamond_pid parameter
Date: Mon, 13 Apr 2026 21:49:58 -0700 [thread overview]
Message-ID: <20260414045002.88110-1-sj@kernel.org> (raw)
DAMON_STAT doesn't provide the pid of its kdamond, unlike DAMON_RECLAIM
and DAMON_LRU_SORT. This makes user-space management of DAMON_STAT
unnecessarily complicated. Provide the information via a new parameter,
namely kdamond_pid, and document it.
SeongJae Park (2):
mm/damon/stat: add a parameter for reading kdamond pid
Docs/admin-guide/mm/damon/stat: document kdamond_pid parameter
