Missing from this email is an assertion:

"I've read through all the code formerly covered by the BKL inside
do_kern_mount() and have satisfied myself that it doesn't need the BKL
any more"

I haven't spotted anything yet, but there's a non-trivial amount of code
which was covered and now isn't.  Someone more familiar with this code
than I am might be able to spot a new race.
