Cover letter [RFC PATCH v2 0/2] mm/damon/stat: add kdamond_pid parameter

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 v1.2
- rfc v1.2: https://lore.kernel.org/[email protected]
- Detect and use fresh kdamond pid.
Changes from RFC v1.1
- rfc v1.1: https://lore.kernel.org/[email protected]
- Close the parentheses of error handling block.
Changes from RFC
