Please do not hesitate to respond to review feedback and post updated versions to replace or incrementally fixup patches in mm-new. The mm-new branch of mm.git is not included in linux-next If a few days of testing in mm-new is successful, the patch will me moved into mm.git's mm-unstable branch, which is included in linux-next Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via various branches at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there most days ------------------------------------------------------ From: SJ Park Subject: mm/damon/core-kunit: extend damos_commit_filter_for() for wrong input Date: Mon, 14 Sep 2026 07:23:24 -0700 damos_commit_filter_for() supposes damos_commit_filter() to always succeed with given inputs. damos_commit_filter() could return an error for invalid inputs. Existing callers always pass only valid inputs, but they may pass invalid inputs in future, for test purposes. Extend the function to be able to be used for wrong inputs-caused error testing.
