Hi It seems that this patch wasn't accepted: https://listman.redhat.com/archives/dm-devel/2023-April/053913.html So, I changed the other patches that depend on it to make the test for empty bio explicitely - I added "if (clone->bi_vcnt > 0)" before "bio_for_each_folio_all". You can send the updated dm-crypt patch and two dm-flakey patches to Linus in this merge window.
