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!
