Patch series "mm/damon: minor fixes and cleanups".
This patchset contains minor fixes and cleanups for DAMON including
- selftest for a bug we found before (Patch 1),
- fix of region holes in vaddr corner case and a kunit test for it
(Patches 2 and 3), and
- documents/Kconfig updates for title wordsmithing (Patch 4) and more
aggressive DAMON debugfs interface deprecation announcement
(Patches 5-7).
This patch (of 7):
Commit d26f60703606 ("mm/damon/dbgfs: avoid duplicate context directory
creation") fixes a bug which could result in memory leak and DAMON
disablement. This commit adds a selftest for verifying the fix and avoid
regression.
