- Remove remaining #ifdef INET.
- Avoid holding locks so we don't need to do KM_NOSLEEP allocations.
- Use a rwlock to protect the accept filter list.
- Make it safe to unload accept filter modules.
- Minor KNF.

* Scary-looking socket locking stubs (changed to KASSERT of locked)
* depends on INET inappropriately (though now you must add new
accept filter names to the uipc_accf.c line in conf/files if
you aren't using dataready or httpready)
* New code uses MALLOC/FREE -- changed to kmem_alloc/kmem_free;
could be pool_cache, these are all fixed-size allocations.
We need to verify that this works as expected with protocols with per-socket
locking, like PF_LOCAL. I'm a little concerned about the case where the
lock on the listen socket isn't the same lock as on the eventual connected
socket.
Typecasting quad_t * to long * and using atomic_add_long can't
possibly be expected to work!
Another fine error caught by the gcc type-punning warning. That
really really should be on by default in the kernel.
static simplelock initializer (and simplelock too). The fastpath
is still lockless, so doesn't make a difference in terms of
performance.
Also fixes a hanging bug if the once routine returned an error.
It does not retry after an error occurs, as I can't really imagine
fruitful semantics for that.
- Change minimal time-quantum to ~20 ms.
- Thus remove unneeded pool in M2, and unused sched_lwp_exit().
- Do not increase l_slptime twice for SCHED_4BSD (regression fix).
UDF. Future users could be msdosfs, ufs, nilfs2 (when ready), cd9660 etc.
Note that its not the same as UFS's DIRHASH support; UFS would need a good
cleanup/splitout of directory operations to adopt to this new directory
hashing support since most directory operations are interweaved with the
vnops itself. This is a TODO.
Let's look for threads in the TARGET process, not in the
debugger process (gdb). Noticed when a KASSERT fired while
running gdb on a threaded app.
I will adjust wrstuden-revivesa-base-3 to include this change.
free a buffer. This will fail if the buffer owner has a chance to
modify the BC_DONTFREE flag before putphysbuf() examines it.
Fix by removing get/putphysbuf() and BC_DONTFREE. Physio_done() now
has an explicit test for a buffer coming from the call of physio().
