From f306b0b41db8c53cf081f9022a03fffdc9386d28 Mon Sep 17 00:00:00 2001 From: SJ Park Date: Wed, 2 Sep 2026 18:03:32 -0700 Subject: [PATCH] mm/damon/reclaim: remove unnecessary damon_call() param validation DAMON_RECLAIM avoids passing NULL or unstarted damon_ctx to damon_call() with its own validation. The validation is no longer needed, because the DAMON core layer now handles the corner cases itself. Remove the unnecessary check.
