Ok, thanks. Most of the breakage that I've seen while testing this (after
I first got it working) was either trivially breaking the build, or
causing lockdep splats for things that are correct with CONFIG_TTY_MUTEX
disabled but violating the lock order with it enabled.

I'm ok with having the series in -next for another kernel to improve
the quality, as long as no new major changes to the tty locking get
merged that break the assumptions I made. Your last series did make
my work easier (or maybe even possible) to get to this point, but most
of the time was spent checking every possible code path by hand to
validate the locking rules, and that would need to be done again
if the code changes.
