Either or, we can decide that once we're done with the patches.

I don't maintain an autofs tree because the module isn't volatile enough
to warrant it. I was sloppy with patches I sent to Linus a few times and
Andrew politely asked me to send them via him, and rightly so, ;)

I guess it comes down to how urgent it is to get these merged since I'd
like to hammer them with my submount test before passing them on and at
this point I don't know when I'll have time to work through that.

I could just set aside some time to run the test a few times and not try
and fix any problems at the time. Point being the test has a habit of
exposing problems that can be difficult to work out let alone fix.
