    Here's a patch for the kernel side.

    Subject: [PATCH] btrfs: Stop trashing 'name' arg of btrfs_name_hash
    From: Alex Chiang <achiang@hp.com>

    In btrfs_name_hash, Local variable 'buf' is declared as

    __u32 buf[2];

    but we then try to do this:

    buf[0] = 0x67452301;
    buf[1] = 0xefcdab89;
    buf[2] = 0x98badcfe;
    buf[3] = 0x10325476;

    Oops. Fix buf to be the proper size.
