Rejected, similar patches is in trunk since some time.
Thanks. I was not aware that the problem had been addressed. Can you point me where to look to see what has been addressed?

There are two patches needed in grub2 to support multi-device btrfs
volumes.

This first patch (previously submitted) involves the parameters passed
to grub2-probe.  If not correctly passed, grub2-probe issues an error
message.  The related problem report is:
   https://bugzilla.redhat.com/show_bug.cgi?id=890955

The second problem involves having a multi-device btrfs volume with
/boot being on the btrfs volume either as part of the root subvolume or
as a separate subvolume.  The result is an error messare at boot time:
     error: no such device: root.
     hit any key to continue

The solution is to modify grub-probe.c so that " " is issued rather than
"\n" for a hint.   The related problem report is:
   https://bugzilla.redhat.com/show_bug.cgi?id=1023161

To minimize problems, the two patches have been attached rather than
provided inline.

Peter, I cc'ed you so you would be aware of these bug reports.  It would
be nice if this was applied to both Fedora 20 and 19.
