But this is the point, right? Yes, but I think it's also the problem. >They won't be identical if different mount options are used, I don't think. If different mount options are used, we'll create different super block instance, and they have the same context, only the difference is each one holds different proc_sb_info. But I think what we really want is only one proc sb instance and create different proc_sb_info if different mount options are used. > >> Here the pre-check seems needless. > Is that new with my patch, or has it always been needless?
