Petersen <martin.petersen@xxxxxxxxxx> Thanks. Btw, below is a trivial patch that fixes two typos in Documentation/block/data-integrity.txt. While reading the paragraph Layered block devices will need to pick a profile that's appropriate for all subdevices. blk_integrity_compare() can help with that. DM and MD linear, RAID0 and RAID1 are currently supported. RAID4/5/6 will require extra work due to the application tag. I was wondering why raid10 is not mentioned and whether someone is currently working on data integrity support for raid levels 4/5/6.
