various people for a while.
ps and friends (libkvm) will need a recompile as some proc structure

This sysctl is used by the diskless startup code and new rc.conf. If
it cannot be found or is empty, the system should revert to using /etc.
where select(2) can return that a listening socket has a connected socket
queued, the connection is broken, and the user calls accept(2), which then
blocks because there are no connections queued.

patch. lf can't be dereferenced after the unload attempt, in case it
was freed. Instead, decrement first and back it out if the unload failed.
This should be relatively immune to races caused by the user since the
userref count will be zero for the duration of the actual unloading and
will stop further kldunload attempts.

throwing away the buffer contents will often result in filesystem
corruption and this solution will at least correctly deal with transient
errors.

B_DELWRI and B_CACHE flags, fixing a bug that showed up with NFS.
Also, a number of cases where manually inserted code has been removed
and replaced with an inline function call giving us better functional
isolation in the source.
descriptor-passing messages was calling sorflush() without checking
to see if the descriptor was actually a socket. This can cause a
crash by exiting programs that use the mechanism under certain
circumstances.
changes to the VM system to support the new swapper, VM bug

cleanup issues.

- Have the syscall lkm support use syscall_register() etc rather than

- Convert the lkm driver to a module.
suggestions from Greg Lehey some time ago. In the face of multiple
potential file formats, try and give a more sensible error than just
ENOEXEC.
XXX a good case can be made that the loading process is wrong - the linker
should locate the file first (using the search paths etc), then run the
loaders to see if they recognize it. While the present system allows for
the possibility of different search paths for different formats, we do not
use it and it just makes things more complicated than they need to be.
* A function device_printf() to make pretty-printing driver messages easier.
* A function device_get_children() to query the children of a device.
* Generic implementations of BUS_ALLOC_RESOURCE and BUS_RELEASE_RESOURCE.
* Change bus_generic_print_child() so that it is actually useful.
It was nay'ed before committing on the grounds that this is not

There is not point in loading gobs of ascii into the kernel when
the only use of that ascii is presentation to the user.
Next thing we'd be adding all section 4 man pages to the loaded
kernel as well.
The argument about KLD's is bogus, klds can store a file in
/usr/share/doc/sysctl/dev/foo/thisvar.txt with a description and
sysctl or other facilities can pick it up there.
Proper documentation will take several K worth of text for many
sysctl variables, we don't want that in the kernel under any
circumstances.
I will welcome any well thought out attempt at improving the
situation wrt. sysctl documentation, but this wasn't it.
