That way fstrim can avoid calling FITRIM several times for the same filesystem. Since I last asked in September, I have actually learned the util-linux already has some support for demangling btrfs subvolume mess used e.g. by lsblk command so maybe fstrim could use it as well and thus avoid calling FITRIM repeatedly for all subvolumes?
