Please let us know when this will be pushed to the kernel, do you have
any thoughts on the planning of this?

As a bcache-tools packager for Fedora I think I should add some package
dependencies which prevent users from accidentally upgrading to that
(breaking) version in the future.

It may also affect other tools like util-linux:
https://github.com/karelzak/util-linux/blob/master/libblkid/src/superblocks/bcache.c

Furthermore I think I should postpone integration of bcache in the
Fedora installer until further notice:
https://bugzilla.redhat.com/show_bug.cgi?id=1003208

Any information in advance is appreciated.
