- Remove g_gate_hold()/g_gate_release() from start/done paths. It saves
...
4 mutex operations per I/O requests.
- Use only one mutex to protect both (incoming and outgoing) queue.
As MUTEX_PROFILING(9) shows, there is no big contention for this lock.
- Protect sc_queue_count with queue mutex, instead of doing atomic
operations on it.
- Remove DROP_GIANT()/PICKUP_GIANT() - ggate is marked as MPSAFE and no
Giant there.

Do a pass over all modules in the kernel and make them return EOPNOTSUPP
...
for unknown events.
A number of modules return EINVAL in this instance, and I have left
those alone for now and instead taught MOD_QUIESCE to accept this
as "didn't do anything".

Introduce a hack that will make geom_gate to work with read-only mounts.
...
Now, when trying to mount file system in read-only mode it tries to
opened a device for writting to be able to update to read-write mode
latter. Ehh.

The biggest issue was that 16-bit atomic operations aren't supported
on all architectures.
