I am sorry, I didnt see that someone created an issue, I believed nobody was using my code. So just 3 years after it is fixed.

[sur5r]

I tried to use it to understand which hash (crc32c or xxhash) might be faster for use with btrfs. Unfortunately, af_alg_test gave inconclusive results with e.g. crc32c sometimes being faster than digest_null, which is hard to believe.

Unfortunately, the kernel module no longer compiles (include file names seem to have changed) and I didn't have enough time to dig into this.

I think it's a useful project and it would be great if it worked on current machines.

[montjoie]

I have the fix for the kernel modules, give me a few time for adding CI tests for it and I will publish the fixes

@sur5r benching BTRFS usage from AF_ALG is not the right way since BTRFS will uses algos inside kernel (AF_ALG is from user space). I think you should simply create a BTRFS partition and try some iozone/bonnie++/etc... bench on it.
