Subject: block: remove the GENHD_FL_HIDDEN check in blkdev_get_no_open
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=a1525fbf1d76783badf95c60e96888a85ad53edc;p=users%2Fhch%2Fblock.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.
