* Btrfs: remove crc32c.h and use libcrc32c directly.David Woodhouse2009-06-101-2/+2
| | | | | | | | | | There's no need to preserve this abstraction; it used to let us use hardware crc32c support directly, but libcrc32c is already doing that for us through the crypto API -- so we're already using the Intel crc32c acceleration where appropriate.

* Switch btrfs_name_hash() to crc32cDavid Woodhouse2008-09-251-1/+6
| | | | | | | | | Date: Tue, 19 Aug 2008 19:21:57 +0100 Using a 64-bit hash as the readdir cookie is just asking for trouble. And gets it, when we try to export the file system by NFS. Signed-off-by: David Woodhouse <David.Woodhouse@intel.com> Signed-off-by: Chris Mason <chris.mason@oracle.com>
* Btrfs: unaligned access fixesDavid Miller2008-09-251-1/+1
| | | | | | | | | | | | | Btrfs set/get macros lose type information needed to avoid unaligned accesses on sparc64. ere is a patch for the kernel bits which fixes most of the unaligned accesses on sparc64. btrfs_name_hash is modified to return the hash value instead of getting a return location via a (potentially unaligned) pointer.
