Subject: mm/damon/paddr: move probe filter handling to ops-common
Date: Wed, 9 Sep 2026 07:04:04 -0700

Probe filter matching logic for anon and memcg type filters in DAMON's
physical address space operation set (paddr) can be reused by virtual
address space operation set (vaddr) in future.  Prepare the future by
moving the code to ops-common.c
