Cover letter [PATCH v2 0/6] Make blkdev_issue_discard() submit aligned discard requests
Users of blkdev_issue_discard(), e.g. blk_ioctl_discard(), expect that this function generates discard request(s) that satisfy block driver alignment requirements. Hence modify blk_bio_discard_split() such that the submitted discard requests are aligned.
Changes compared to v1:
- Moved the code to split discard requests from blkdev_issue_discard() into blk_bio_discard_split().
