Cover letter [PATCH 0/2] Docs/admin-guide/mm/damon: warn commit_inputs vs other params race
Writing 'Y' to the commit_inputs parameter of DAMON_RECLAIM and DAMON_LRU_SORT, and writing other parameters before the commit_inputs request is completely processed can cause race conditions. While the consequence can be bad, the documentation is not clearly describing that. Add clear warnings.
