Hi!
I updated the Fedora 20 & rawhide package for bcache-tools:
https://admin.fedoraproject.org/updates/bcache-tools-0-0.11.20130909git.fc20
It's an update to the latest git / gist sources for bcache-tools an
bcache-status. Some of the patches it includes to make it run on Fedora
are explained below.

bcache-tools-20130827-udevfix.patch
=======================
On Fedora only 'early' udev rules files run /usr/sbin/blkid and the rest
of the rules files use the results. This patch removes the call to
/usr/sbin/blkid and (more important) makes sure that probe-bcache does
not print overlapping variable names. This is needed until util-linux
itself supports bcache, after that there's no need to call
probe-bcaches at all.

bcache-tools-20130827-register.patch
=======================
Fedora needs full path names to call /sbin/ binaries from udev, this is
fixed in this patch. Also errors are suppressed when a device is
registered twice.
