Two kinds of objects there - ptmx and everything else (pty). The former is
created on mount and kept until the fs shutdown; the latter get created
and removed by tty layer (the references are borrowed into tty->driver_data).
The reference to ptmx dentry is also kept, but we only ever use it to
find ptmx inode on remount.
* turn d_add() into d_make_persistent() + dput() both in mknod_ptmx() and
in devpts_pty_new().
* turn dput() to d_make_discardable() in devpts_pty_kill().
* switch mknod_ptmx() to simple_{start,done}_creating().
* instead of storing in pts_fs_info a reference to ptmx dentry, store a reference
to its inode, seeing that this is what we use it for.
