Add bufobj_wref(), bufobj_wdrop() and bufobj_wwait() to handle the write
count on a bufobj. Bufobj_wdrop() replaces vwakeup().
Use these functions all relevant places except in ffs_softdep.c where
the use if interlocked_sleep() makes this impossible.
Rename b_vnbufs to b_bobufs now that we touch all the relevant files anyway.
Initialize the bo_mtx when we allocate a vnode i getnewvnode() For
now we point to the vnodes interlock mutex, that retains the exact
same locking sematics.
Move v_numoutput from vnode to bufobj. Add renaming macro to
postpone code sweep.
Add new include file <sys/bufobj.h> which will contain the gory
details on the new buffer-cache object. (see comments in file
about the direction this is moving).
Include it from <sys/vnode.h> for now to avoid munging a lot of files
which can later be munged back.
Embed a bufobj in vnode.
Move the buf splay trees from the vnode to the bufobj.
Alias the fields to avoid sweeping code yet.
Hide vnode and bufobj behind
#if defined(_KERNEL) || defined(_KVM_VNODE)
to discourage userland voyeurism.
modes on a tty structure. Both the ".init" and the current settings
are initialized allowing the function to be used both at attach and
open time.
The function takes an argument to decide if echoing should be enabled
by default. Echoing should not be enabled for regular physical
serial ports unless they are consoles, in which case they should
be configured by ttyconsolemode() instead.
Use the new function throughout.
right bits rather than piggy-backing on the V* rights defined in
vnode.h. The mac_bsdextended bits are given the same values as the V*
bits to make the new kernel module binary compatible with the old
version of libugidfw that uses V* bits. This avoids leaking kernel
API/ABI to user management tools, and in particular should remove the
need for libugidfw to include vnode.h.

a new, post-RELENG_5 assertion in vm_page_io_finish(). (I am in the
process of transitioning the responsibility for synchronizing access to
various fields/flags on the page from the global page queues lock to the
per-object lock.)

this may fix it. At least this is needed to have em(4) work properly

explore more mature APIs for unregistering the protocol and then
draining consumers, or an atomic test-and-unregister mechanism.
