[PATCH 0/2] Remove custom crc32c init code from btrfs

[Nikolay Borisov]

So here is a small 2 patch set which removes btrfs' manual initialisation of 
the lower level crc32c module. Explanation why is ok can be found in Patch 2/2.

Patch 1/2 just adds a function to the generic crc32c header which allows 
querying the actual crc32c implementaiton used (i.e. software or hw-accelerated)
to retain current btrfs behavior. This is mainly used for debugging purposes 
and is independent.
