But then I can't turn a nocompress option back to compress via > remount. This is possible with Arnd's patch. This happens for space_cache mount option: ierdnac-hp ~ # mount -o remount,space_cache,nospace_cache /mnt/btrfs/ Also there are mount option that can't be enabled/disabled by remount like: nobarrier - > "barrier" mount option doesn't exists ssd -> "nossd" doesn't exists noacl, user_subvol_rm_allowed, autodefrag, inode_cache, check_int, check_int_data. For some of these(ex: nossd,barrier) I think it would be usefull to have the reverse action. What do you think ?
