Subject: [PATCH RFC 0/7] Introduce new async/sync compression APIs

Happy New Year!

This patchset is to introduce new compression APIs. It supports async/sync
compression although there is no async compression driver yet. But, async
APIs can be used as front-end to sync compression algorithm. Major change
is that now APIs are stateless. Instead of previous implementation, tfm
objects doesn't embedded any context so we can de/compress concurrently
with one tfm object. Instead, this de/compression context is coupled with
the request. This architecture change will make APIs more flexible.

This is just a RFC so commit description isn't sufficient. If Herbert
confirms that this is what he expect, I will respin the series with proper
commit description and adding more algorithm support.

Thanks.

Joonsoo Kim (6):
  crypto/compress: remove unused pcomp interface
  crypto/compress: introduce sychronuous compression API
  crypto/lzo: support SCOMPRESS alg type
  crypto: testmgr: add scompress/acompress test
  crypto/compress: add algorithm type specific flag, DECOMP_NOCTX
  crypto/lzo: add CRYPTO_ALG_SCOMPRESS_DECOMP_NOCTX cra_flags

Weigang Li (1):
  crypto: add asynchronous compression support
