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.
