Subject: mm/damon/core: hide damon_add_region()
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9cf7ef2d6665dff35b3b522c84509c2d256bf3aa;p=thirdparty%2Flinux.git

mm/damon/core: hide damon_add_region()

damon_add_region() is being used by only DAMON core, but exposed to DAMON
API callers.  Exposing something that is not really being used by others
will only increase the maintenance cost.  Hide it.
