[RESEND PATCH v3] crypto: add zBeWalgo compression for zram

2018-03-06 Thread Benjamin Warnke
Currently ZRAM uses compression-algorithms from the crypto-api. ZRAM compresses each page individually. As a result the compression algorithm is forced to use a very small sliding window. None of the available compression algorithms is designed to achieve high compression ratios with small inputs.
