Here's a slightly updated version of the BTRFS snappy interface. snappy is a faster compression algorithm that provides similar compression as LZO, but generally better performance.
This version has:
- Ported to latest tree - Extensive testing and benchmarking (in its 3.0 based incarnation) - A few cleanups - Adds a minor performance improvement
Should be ready for pulling into the btrfs tree now. The crypto parts have been acked by Herbert.
The following changes since commit 2485a4b610171f4e1c4ab0d053569747795c1bbe:
