This was my plan, but btrfstune probably isn't the best program to do it (the ext2 tune program is mostly aimed at the super block level things). I think it would be better to make a setattr style program to call the ioctls. There is already a per file compression flag, and the code should already be checking it. -chris -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
