EL7 would get that backport independently of a new release.
That's now tracked at https://bugzilla.redhat.com/1197463

Wow. I just spent about three hours investigating and came up with this
little patch for coreutils-8.20:
----------- sample starts -------------------------------
--- coreutils-8.21/src/df.c 2013-02-05 01:40:31.000000000 +0200

@@ -624,8 +624,8 @@ filter_mount_list (void)
}
else
{

- if (strchr (me->me_devname, '/'))

{
/* ... try to find its device number in the devlist. */
for (devlist = devlist_head; devlist; devlist = devlist->next)
----------- sample ends ------------------------------
And all in vain because the 'df' utility in the latest coreutils git-repo
already works correctly. :-)
So sorry for the noise.
Do you have plans to release coreutils-8.24 soon? The
coreutils-8.22.11.el7 on Red Hat Enterprise Linux 7 / CentOS 7 is
currently broken.

vmk
