Ok. Got this to reproduce. Will hopefully have a fix for your soon.

Thanks for looking at it! It had been a while since I had problems with
rt so I could not understand why I could not login :-)

Bah! I should have caught this faster. I kept thinking it had to be some
missed unlock of the sbi->fs_lock, but it ends up its just the
autofs4_lock.
Apparently the conversion from using the dcache_lock -> autofs4_lock
forgot that this function already grabs the autofs_lock for a small
moment, so we end up grabbing the lock, then a moment later grab it
again. Splat.
This patch should resolve it.

I'm still having problems when trying to use autofs, even with your

Oof.. More of the same autofs4_lock misuse. I skimmed over the rest of
its use, and it seems ok, so hopefully we won't hit any more problems
caused by it.
Here's both autofs4_lock changes together.
