Cover letter [PATCH v2 0/4] rewrites discard support
Quoted 17 lines · Ming Lin

From: Ming Lin <ming.l at ssi.samsung.com>

This rewrites nvme_setup_discard() with blk_add_request_payload(). And moves it to common code so fabrics driver can also use it.

v2:
- add helper nvme_map_len()
- allocates only 16 bytes for discard payload
- moves command setup to common helper nvme_setup_cmd()
- returns BLK_MQ_RQ_QUEUE_BUSY when out of memory

Ming Lin (4):
nvme: add helper nvme_map_len()
block: add offset in blk_add_request_payload()
nvme: rewrite discard support
nvme: add helper nvme_setup_cmd()

Looks good to me, I'll queue it up for 4.7. Thanks.
