My Seagate ST32430N now sees about 50% greater throughput (about 97% as
fast as IRIX can push it). However, there appear to be other performance
issues with the driver as other disks perform significantly worse than they
should, with or without this change.

for nodes upon return from the userspace. Currently it can be used
to indicate that the file server should be notified of "inactive"
in case the file server has opted to not receive inactive every
time the reference count for a vnode drops to zero. (inactive is
a common event, almost never requires any action and must be executed
sychronously, so it is wasteful).
While doing this, cleanup the release-relock nonsense from the
vntouser*() arguments. It was never enabled and the whole LOCKEDVP()
concept was very broken to begin with.

The old split (find_stopped_child) could be removed.
amd64 seems to run netbsd32, linux and linux32 emulations. sparc64 compiles.
all metadata info cached in the kernel while we're setattr'ing in
any case. Solves problems such as truncate (via extend-by-write)
+ chmod resulting in EPERM because the file was already read-only
when the actual truncate was flushed out of the kernel in fsync.
avoid an indirect function call by comparing the family, length,

For ISO, actually use sockaddr_iso_cmp, for a change. Thanks to
yamt@ for pointing out my error.
Fix a defect in the locking of file descriptors as we delegate a
UDP socket from userland to the kernel. Move sc_fp out of sc_soparm.
Synchronize access to sc_fp by gre_ioctl() and the kernel thread
using a condition variable. For simplicity's sake, make it the
kernel helper thread's responsibility to close its UDP socket.
While I am here, introduce an rtentry pointer, 'rt', and set it
equal to ip6_forward.ro_rt. Replace several occurrences of
'ip6_forward.ro_rt' with 'rt'.
instead of before, because if_detach() may cause the cache to be
reloaded. (I already fixed this in both etherip(4) and gre(4).
Ewww, rampant code duplication.)

- Set a lower priority for AIO-worker thread, because current could cause
interactivity problems (eg. with qemu - thanks <xtraeme> for testing).
Mark it as XXX for now - after priority model change, this should
be reconsidered anyway.
- Do not copyout() with lock held in sys_aio_cancel().
- Fix a leak of the lock in aio_process().
- Check for any error of cv_wait_sig().
- Cache p->p_aio in aio_exit().
Thanks <ad> for catching the issues!
