__blkdev_issue_discard() always returns 0, making all error checking at call sites dead code. For dm-thin change issue_discard() return type to void, in passdown_double_checking_shared_status() remove the r assignment from return value of the issue_discard(), for end_discard() hardcode value of r to 0 that matches only value returned from __blkdev_issue_discard().
