From: SeongJae Park <sj@kernel.org> mainline inclusion from mainline-v5.16-rc5 commit 09e12289cc044afa484e70c0b379d579d52caf9a category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I4RTX9 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... -------------------------------- The DAMON virtual address space monitoring primitive prints a warning message for wrong DAMOS action. However, it is not essential as the code returns appropriate failure in the case. This commit removes the message to make the log clean.
