Fwif and if I understand this correctly then this would mostly matter for stacking filesystems or filesystems that already have access to the relevant struct vfsmount they need to talk about anyway. It's not about passing struct vfsmount into inode methods themselves which would be a bad idea. Meaning Amir's change would not require or cause vfsmounts to be made accessible where they arent't already.
