SeongJae Park ccd84befd3 selftests/damon: test debugfs file reads/writes with huge count ... BugLink: https://bugs.launchpad.net/bugs/1956302 commit b4a002889d upstream. DAMON debugfs interface users were able to trigger warning by writing some files with arbitrarily large 'count' parameter. The issue is fixed with commit db7a347b26 ("mm/damon/dbgfs: use '__GFP_NOWARN' for user-specified size buffer allocation"). This commit adds a test case for the issue in DAMON selftests to avoid future regressions.
