The patches are now merged into 3.11. > It looks like lz4 and lz4hc will be provided. Regarding HC mode, there are some core compression code changes needed in order to fully utilize the its potential, namely larger chunk size that's compressed at a time. There was some tiny yet measurable gain of HC against ordinary mode compared on current 4k-at-a-time implementation, but the space savings did not justify the speed drop of HC mode. I can't say if the patchset will be ready for 3.12 though. david -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
