Hi,
so here it is, LZ4 compression method inside btrfs. The patchset is based on
top of current Chris' for-linus + Andi's snappy implementation + the fixes from

Adjusted a few defines to compile. The on-stack context allocation is
disabled and either LZ4_compress64kCtx or LZ4_compressCtx must be used.
