[PATCH/RFC 0/7] Partial (de)compression API

[Geert Uytterhoeven <Geert.Uytterhoeven@sonycom.com>]

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

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

Changes since last version (2008-12-17):
  - Model the "pcomp" crypto interface on the new crypto types,
  - Remove the comp_request parameter from *_{,de}compress_init(),
  - Update for recent Squashfs changes (Squashfs is now in mainline).

Thanks for your comments!
