[parted-devel] [PATCH 2/2] Test the correctness of btrfs probing

[Luca Bruno]

commit 7b7ffc2234792e9848bae9264a0fce7fdab72b0c
Author: Luca Bruno <lucab at debian.org>
Date:   Sun Mar 15 10:54:03 2009 +0100

    Test the correctness of btrfs probing
    
    Create a simple btrfs file system (no subvolumes nor
    multidevices) and check if it's correctly recognized.
    Minimum size forced, as mkfs.btrfs can't currently
    create file systems smaller than 256MB.
