Subject: mm/damon/paddr: use a separate function for 'DAMOS_PAGEOUT' handling
Date: Mon, 13 Jun 2022 19:22:55 +0000
This commit moves code for 'DAMOS_PAGEOUT' handling of the physical
address space monitoring operations set to a separate function so that its
caller, 'damon_pa_apply_scheme()', can be more easily extended for
additional DAMOS actions later.
