Subject: [PATCH/RFC 0/8] Partial decompression API
Sender: linux-kernel-owner@vger.kernel.org

The following patch series adds support for partial (de)compression to the
CRYPTO API, and modifies SquashFS 4 to use this:
  [1] crypto: testmgr - Correct comment about deflate parameters
  [2] crypto: compress - Add pcomp interface
  [3] crypto: testmgr - Add support for the pcomp interface
  [4] crypto: api - Add type init function to crypto_tfm
  [5] crypto: api - Export pcomp through comp
  [6] crypto: deflate - switch to pcomp
  [7] crypto: testmgr - swith deflate test to pcomp
  [8] squashfs: Make SquashFS 4 use the new pcomp crypto interface

All patches are relative to cryptodev-2.6.git, except for the last one, which
is relative to squashfs-2.6.git.

The first patch is independent and can be applied immediately, but I included
it in this series to avoid rejects.

The backwards-compatibility layer has been tested with IPComp and UBIFS.

Changes since last version (2008-11-24):
  - Add a new "pcomp" crypto interface, instead of modifying the existing
    "comp" interface, with a compatibility layer,
  - Modify the existing "deflate" module, instead of adding a new "zlib"
    module,
  - Add support for the configuration of (de)compression parameters,
  - Separate allocation for compression and decompression, to avoid memory
    wastage.

Thanks for your comments!
