Neat feature! Tested and it appears to function correctly. I just noticed a simple grammar error in man page update.

Thanks for taking a look Kristof,

Sure, I will take a look

Hi from me as well,

could you write an email to me and freebsd-virtualization@freebsd.org with
the necessary steps to re-produce the problem?

Updated to today's head branch. Please review

Thanks a lot, Nikos.

I've fixed the problem of sleeping in UMA on kldunload. It was out the scope of the patch. I also committed the first part of the patch - mutexes initialization.

Nikos, can you please svn update and then arc update, so that updated patch is posted here?

I tested this patch.

# kldload pf
# kldunload pf
kldunload: can't unload file: Device busy

The fact that the pf module cannot be unloaded was one of the
reasons that @glebius used to back out the entire changeset last time
I committed your pf changes. Can you fix this?

This guilde is definitely invaluable, I have seen it. It would be great if we could move it in the source tree.

Please review this. It updates the previous patch, with another way to unload pf.

Yes, I am trying to fix the issues. It needs more work. I will update when I have a new patch

Don't we still need to do all of this somewhere?

Nikos,

acking that I see the patches. Right now I'm waiting for pf to stablize after
recent patches to fragment handling. Kristof is working on the known problem.
Meanwhile you can finish your patch moving from "almost there" to "there" :)
