Subject: [PATCH] udev: do not rely on DRIVER variable
Git-commit: b48c30983b1510d94745bd07494fa81a68a5896e
Patch-mainline: bcache-tools-1.1
References: bsc#1139948

The DRIVER variable will only be set on a single event (when the
module creates the first instance?). Any subsequent udev event, e.g. a
change event for bcache0, does not have the DRIVER tag set. In fact,
most events don't. (This can be reproduced with `udevadm trigger`.)
This leads to a change in the contents of the SYMLINK variable which
leads to removal of /dev/bcache/, since DRIVER is not set.

Don't even bother to create such a volatile /dev/bcache/ in the
first place so users don't go chasing after it.
