The first one is a repost of my BLKDEV_DISCARD_ZERO with the spelling fixes suggest from Martin, the second one just drops the -EOPNOTSUPP special casing in blkdev_issue_write_same. Note that the patches are against the block for-next tree, and unfortunately we have diverged significantly from 4.7 in this area: 4.7 has the missing bio_put for the sumbmit_bio_wait callers, and 4.8 has the various req_op changes, including a new calling convention for __blkdev_issue_zeroout. I'm not sure how to best sort this mess out, but I really think we need the bio_put in the for-4.8 tree as well, and we should probably bring the changed __blkdev_issue_discard calling convention into 4.7 as well. Suggestion for how to best handle this? -- To unsubscribe from this list: send the line "unsubscribe linux-block" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
