[RFC PATCH v1.2 0/2] mm/damon/stat: add kdamond_pid parameter

[SeongJae Park]

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.

Changes from RFC v1.1
- rfc v1.1: https://lore.kernel.org/20260414235912.98174-1-sj@xxxxxxxxxx
- Close the parentheses of error handling block.
