Hi,
the stable tag was missing for the following commit:
commit 2a07bb64d801 ("s390/dasd: Remove DMA alignment")
The change needs to be applied for kernel 6.0+ essentially reverting
bc792884b76f ("s390/dasd: Establish DMA alignment").
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
