The compression infrastructure needs a few updates first, the on-disk format of the compressed chunks has to be extended to hold large contiguous chunks. (Other compressors would benefit from the changes, so it's not just because of lzma.) First tests showed that it was really slow for normal use, but for backup purposes it might be not that bad. david -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
