Thank you for this patch! Could you please elaborate why this change is needed, though? What is the user impacting issue that this patch is fixing? Is this fixing a false positive or negative test results? Or, just making the allocation failure easier to find? > > Fixes: b5906f5f7359 ("selftests/damon: add a test for > update_schemes_tried_regions sysfs command") > Fixes: c94df805c774 ("selftests/damon: implement a program for even-numbered > memory regions access") If this patch is only making the allocation failure easier to detect, I think it is an improvement rather than a fix. If that's the case, I think we don't need above Fixes: tags. If this is a real bug fix, maybe it deserves stable@ porting. Please separate this into two patches for each bug and Cc stable@ for easy stable@ porting. Thanks, SJ [...]
