[PATCH 09/10] mm/damon/sysfs: do not directly access damon_ctx->ops
From: SJ Park
Date: Tue Jul 14 2026 - 10:39:38 EST
damon_ctx->ops field is intended to be used by only the DAMON core
layer. DAMON_SYSFS is directly reading the field to find if it is for
physical address monitoring, though. Use the API function for the
purpose, damon_target_has_pid(), instead.
