From: Sergey Senozhatsky
Date: Wed Feb 12 2014 - 14:43:32 EST


This patchset introduces zcomp compression backend abstraction
adding ability to support compression algorithms other than LZO;
support for multi compression streams, making parallel compressions
possible.

Diff from v3:
-- renamed compression backend and working memory structs as requested
by Minchan Kim; fixed several issues noted by Minchan Kim.

Sergey Senozhatsky (4):
zram: introduce compressing backend abstraction
zram: use zcomp compressing backends
zram: support multi compressing buffers
zram: document max_comp_streams
