This is where I stopped reading this patch series.

No.

We want to get *rid* of the idiotic "primary instance" crap.

The whole and only point of doing the "which pts filesystem am I
associated with" for ptmx is to stop the idiotic "one devpts is
pecial".

I don't want to see 16 random patches.

I want to see *one* patch that makes /dev/ptmx look up the pts
filesystem, and be done with it.

Plonk.
