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.
