Subject: fs: bdev: fix conflicting comment from lookup_bdev
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=057178cf518e699695a4b614a7a08c350b1fdcfd;p=linux.git

fs: bdev: fix conflicting comment from lookup_bdev

We switched to directly use dev_t to get block device, lookup changed the
meaning of use, now we fix this conflicting comment.
