If you want to zero use REQ_OP_WRITE_ZEROES.. Yes, I understand that part and it's what the earlier conversion of IBLOCK to use blkdev_issue_zeroout() already does. Once the blkdev_issue_zeroout() conversion is in place then LBPRZ can always be set to one for IBLOCK using blkdev_issue_zeroout(). The point is this is not in -rc1, which as-is breaks LBPRZ compat for a release. -- To unsubscribe from this list: send the line "unsubscribe target-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
