Now no more complain from __blkdev_issue_discard() for the improper value of discard granularity. This issue is exposed after commit b35fd7422c2f ("block: check queue's limits.discard_granularity in __blkdev_issue_discard()"), a "Fixes:" tag is also added for the commit to make sure people won't miss this patch after applying the change of __blkdev_issue_discard().
