I am quite proud of the linux boot time pitting against other OS. Even
with 10 partitions. Linux can boot up in just a few seconds, but now
you're saying that we need to do this semaphore check at boot up. By
doing so, it's inducing additional 4 seconds during boot up.

What about moving the locking mechanism to the "mount" program itself?
Won't that be more feasible?

As for the cases of simultaneous mounts, it's usually administrator
that's doing something bad. I would say this is not a kernel issue.
