From 61879eed1f180ff92c2324b24d06eeddcc9256bd Mon Sep 17 00:00:00 2001 From: SeongJae Park Date: Mon, 26 Aug 2024 20:03:34 -0700 Subject: [PATCH] mm/damon/dbgfs-test: skip dbgfs_set_init_regions() test if PADDR is not registered The test depends on registration of DAMON_OPS_PADDR. It would be registered only when CONFIG_DAMON_PADDR is set. DAMON core kunit tests do fake ops registration for such case. However, the functions for such fake ops registration is not available to DAMON debugfs interface. Just skip the test in the case.
