Yes, that's my plan - get rid of the 'struct path' entirely, make 'driver_data' point to just the dentry, and then at TIOCGPTPEER time just re-create the path by looking up the vfsmount again (by doingf that "pts" lookup again)
that "pts" lookup again)
It should all be _fairly_ straightforward, but it's definitely a rather bigger change than that "just fix the path" patch was.
