Subject: dasd_format(): killing the last remaining user of ->bd_inode
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=463b3162c96dd5986adb5790ed889c785fefeede;p=linux.git

dasd_format(): killing the last remaining user of ->bd_inode

What happens here is almost certainly wrong.  However,
	* it's the last remaining user of ->bd_inode anywhere in the tree
	* it is *NOT* a fast path by any stretch of imagination
