Subject: mm/damon: remove damon_operations->cleanup()
Date: Sat, 17 Jan 2026 09:52:48 -0800

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.
