Subject: block: remove the GENHD_FL_HIDDEN check in blkdev_get_no_open
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=140862805affca32b3c92a9a7643a7ee6d6ab278;p=uclinux-h8%2Flinux.git

block: remove the GENHD_FL_HIDDEN check in blkdev_get_no_open

Hidden gendisks never hash the block device inode, so this can't happen.
