[PATCH 0/2] Docs/admin-guide/mm/damon: warn commit_inputs vs other params race

[SeongJae Park]

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.

The issue was discovered [1,2] by sashiko.
