This patch allow zcache to use the crypto API for page compression. It replaces the direct LZO compress/decompress calls with calls into the crypto compression API. The compressor to be used is specified in the kernel boot line with the zcache parameter like: zcache=lzo or zcache=deflate. If the specified compressor can't be loaded, zcache uses lzo as the default compressor.
