mm/damon/paddr: make supported DAMOS actions of paddr clear
Patch series "mm/damon: cleanup code".
DAMON code was not so clean from the beginning, but it has been too much
nowadays, especially due to the duplicates in DAMON_RECLAIM and
DAMON_LRU_SORT. This patchset cleans some of the mess.
This patch (of 22):
The 'switch-case' statement in 'damon_va_apply_scheme()' function provides
a 'case' for every supported DAMOS action while all not-yet-supported
DAMOS actions fall through the 'default' case, and comment it so that
people can easily know which actions are supported. Its counterpart in
'paddr', 'damon_pa_apply_scheme()', however, doesn't. This commit makes
the 'paddr' side function follows the pattern of 'vaddr' for better
readability and consistency.
