The patch fixes filesystem errors especially for XFS when DASD devices are formatted with a blocksize smaller than 4096 bytes. The commit 2a07bb64d801 ("s390/dasd: Remove DMA alignment") should apply cleanly for kernel 6.9+. There was a refactoring happening at the time with the following two commits (just for context, not required as prereqs!): commit 0127a47f58c6 ("dasd: move queue setup to common code") commit fde07a4d74e3 ("dasd: use the atomic queue limits API") For everything before 6.9 a simple git revert for commit bc792884b76f ("s390/dasd: Establish DMA alignment") should work just fine. If you run into any conflicts, need separate patches, or have any questions, please let me know. Thanks a lot and apologies for the inconvenience! regards, Jan
