It may be decided that it is a dup of the one Darren already pointed to but I would like to see someone prove that. It is not clear to me why the blockstats feature could not be supported on btrfs so could justify seperate tracking anyway. (The resolution of the one Darren pointed to will be to just disable blockstats for filesystem that don't have block devices.) > 2.
