Subject: mm/damon/core: split out scheme stat update logic into a new function
Date: Wed, 26 Oct 2022 22:59:34 +0000

The function for applying a given DAMON scheme action to a given DAMON
region, 'damos_apply_scheme()' is not quite short.  Make it better to read
by splitting out the stat update logic into a new function.
