Add such a paragraph to the flock(2) manpage for the
sake of consistency.

and cannot handle it going away, add an explicit reference to the kobj
class inside each linker class. Without this, a class with no modules
loaded will sit with an idle refcount of 0. Loading and unloading
a module with it causes a 0->1->0 transition which frees the ops table
and causes subsequent loads using that class to explode. Normally, the
"kernel" module will remain forever loaded and prevent this happening, but
if you have more than one linker class active, only one owns the "kernel".
This finishes making modules work for kldload(8) on amd64.

Minor optimization of a couple of calls to fifo_cleanup() from
fifo_open().

Bruce also points out that a number of the pointer == NULL tests
are probably nonsense because the respective checks are already
done at upper layers.

This is much faster -- about twice as fast in some crude benchmarks.
