Btrfs-progs: add test for receive
Add a test for a scenario that used to fail due to find_mount_root() incorrectly determining the mount point for the receive path due to the fact that a different mount point with a path that is a prefix of the receive path exists. This is fixed by a recent patch titled: "Btrfs-progs: fix mount point detection due to partial prefix match" Reported-by: David Disseldorp <ddiss@suse.com> Signed-off-by: Filipe Manana <fdmanana@suse.com> [ adjustments to make the test work when hosted on NFS ] Signed-off-by: David Sterba <dsterba@suse.com>
