I have started looking at it but just the autofs4_lock.

As you know, we have some significant autofs changes in progress, so I
don't want to spend a huge amount of time testing (and the testing does
take a long time) against source that will be very different. So far I
can't see that the autofs4_lock will introduce any problem so I want to
leave it for now and (probably) eliminate it in the new code since that
will need changes as well and will need to be re-tested.

I'd appreciate it if you could find time to reply to David's questions
about the changes to our d_automount patch series. Although, based on
our previous discussion, I think he has it about right, but a word or
two from you would be really helpful.
