Subject: Re: struct backing_dev - purpose and life time rules

In addition to these gem's there's an even worse issue in blk cfq,
introduced in commit
"blkio: Export disk time and sectors used by a group to user space"
which parses the name inside the backing_dev sysfs device back into a
major / minor number. Given how obviously stupid this is, and given
the whack a mole blkiocg is I'm tempted to simply break it and see if
anyone cares.
