Thanks! Just as another heads up, I decided to run a full regression test suite on 6.1.167-rc1 with those three reverts, and there ar still some crashes with generic/051 and ext4/039: ext4/4k: 711 tests, 1 errors, 83 skipped, 4645 seconds Errors: generic/051 ext4/1k: 636 tests, 7 failures, 1 errors, 78 skipped, 5612 seconds Errors: ext4/039 ext4/encrypt: 679 tests, 1 errors, 215 skipped, 3343 seconds Errors: generic/051 ext4/ext3conv: 706 tests, 1 errors, 85 skipped, 5282 seconds Errors: generic/051 ext4/adv: 713 tests, 13 failures, 1 errors, 91 skipped, 4944 seconds Errors: generic/051 ext4/dioread_nolock: 711 tests, 1 failures, 1 errors, 83 skipped, 5518 seconds Errors: generic/051 ext4/data_journal: 635 tests, 6 failures, 1 errors, 151 skipped, 4105 seconds Errors: ext4/039 ext4/bigalloc_4k: 604 tests, 1 errors, 79 skipped, 4876 seconds Errors: ext4/039 ext4/bigalloc_1k: 682 tests, 6 failures, 1 errors, 106 skipped, 5454 seconds Errors: generic/051 ext4/dax: 705 tests, 10 failures, 1 errors, 207 skipped, 3249 seconds Errors: generic/051 I'll start trying to bisect this as I have time today. Are you going to put out another rc and restart the 48 hour testing clock? - Ted P.S.
