[PATCH] Allow watching of vnodes that reside on non-UFS filesystems with kqueue

Hello,

The patch at 
http://people.freebsd.org/~ssouhlal/testing/kqueue-hooks-20050412.diff 
allows watching vnodes on non-UFS filesystems with kqueue.

It moves the VN_KNOTE calls to pre and post VOP_* hooks. These hooks 
are currently used for VFS lock debugging only, but I made them 
unconditional. I think that they we could eventually move the 
mac_check_vnode_* calls into them too, with a bit of work.

I would like to commit this to HEAD, if there are no objections.

Bye,
