    SubjectUpdated btrfs/crypto snappy interface ready for merging
    Date
    Here's a slightly updated version of the BTRFS snappy interface.
    snappy is a faster compression algorithm that provides similar
    compression as LZO, but generally better performance.

    This version has:

    - Ported to latest tree
    - Extensive testing and benchmarking (in its 3.0 based incarnation)
    - A few cleanups
    - Adds a minor performance improvement

    Should be ready for pulling into the btrfs tree now.
    The crypto parts have been acked by Herbert.

    The following changes since commit 2485a4b610171f4e1c4ab0d053569747795c1bbe:

    Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input (2012-01-12 12:40:41 -0800)

    are available in the git repository at:

    git://git.kernel.org/pub/scm/linux/kernel/git/ak/linux-misc snappy
