mm/damon: remove damon_operations->cleanup()
Patch series "mm/damon: cleanup kdamond, damon_call(), damos filter and
DAMON_MIN_REGION".
Do miscellaneous code cleanups for improving readability. First three
patches cleanup kdamond termination process, by removing unused operation
set cleanup callback (patch 1) and moving damon_ctx specific resource
cleanups on kdamond termination to synchronization-easy place (patches 2
and 3). Next two patches touch damon_call() infrastructure, by
refactoring kdamond_call() function to do less and simpler locking
operations (patch 4), and documenting when dealloc_on_free does work
(patch 5). Final three patches rename things for clear uses of those.
Those rename damos_filter_out() to be more explicit about the fact that it
is only for core-handled filters (patch 6), DAMON_MIN_REGION macro to be
more explicit it is not about number of regions but size of each region
(patch 7), and damon_ctx->min_sz_region to be different from
damos_access_patern->min_sz_region (patch 8), so that those are not
confusing and easy to grep.
This patch (of 8):
damon_operations->cleanup() was added for a case that an operation set
implementation requires additional cleanups. But no such implementation
exists at the moment. Remove it.
