Raid0 only sets max_discard_sectors, but does not force alignment of discard requests. Discard request will be broken up into chunk-sized REQ_DISCARD by blkdev_issue_discard(), but if the sector is not chunk-aligned, each REQ_DISCARD to raid0 will all remain unaligned and raid0 will ned to split them all. This patch will prevent splitting of REQ_DISCARD requests. -eivind
Which patch would that be, exactly. :-) NeilBrown
