initializations but we did have lofty goals and big ideals.
Adjust to more contemporary circumstances and gain type checking.
Replace the entire vop_t frobbing thing with properly typed
structures. The only casualty is that we can not add a new
VOP_ method with a loadable module. History has not given
us reason to belive this would ever be feasible in the the
first place.
Eliminate in toto VOCALL(), vop_t, VNODEOP_SET() etc.
Give coda correct prototypes and function definitions for
all vop_()s.
Generate a bit more data from the vnode_if.src file: a
struct vop_vector and protype typedefs for all vop methods.
Add a new vop_bypass() and make vop_default be a pointer
to another struct vop_vector.
Remove a lot of vfs_init since vop_vector is ready to use
from the compiler.
Cast various vop_mumble() to void * with uppercase name,
for instance VOP_PANIC, VOP_NULL etc.
Implement VCALL() by making vdesc_offset the offsetof() the
relevant function pointer in vop_vector. This is disgusting
but since the code is generated by a script comparatively
safe. The alternative for nullfs etc. would be much worse.
Fix up all vnode method vectors to remove casts so they
become typesafe. (The bulk of this is generated by scripts)
Users should move to the new geom_vinum implementation instead.
The refcount logic which is being added to devices to enable safe module
unloading and the buf/vm work also in progress would require a major rework
of the (old)-vinum code to comply with the new semantics.
The actual source files will not be removed until I have coordinated with
the geomvinum people if they need any bits repo-copied etc.
This is necessary so source upgrades use the correct binary.
MFC after: 3 days
For the record: Problem spotted by Scott Long, who mentioned
that source upgrades from 4.7 to recent 5.x and 6.0 are broken.
Detailed analysis shows that 4.7 has a broken make(1) binary.
A breakage was fixed in RELENG_4 in make/main.c,v 1.35.2.7 by
imp@, though the commit log erroneously stated "MFC 1.68"
while in fact it should have been spelled as "MFC 1.67".
Now that the devs files are marked before-depend, we can remvoe them
from a few places they were explicitly mentioned (along with
BEFORE_DEPEND).
Noticed by: bde
delete it each time its run and have it regenerated each time by make.
I used a quick hackish script rather than putting it in the files file
and used the before-depend rule to avoid the depend/no-depend hacks.
uncovering some interesting problems. Be conservative and effecitvely
disable this by default. Interested parties may still define
KERNBUILDDIR by hand to achive the same effect.
I plan on referting this change after 5.2 is released, or sooner if
the issues with building releases are resolved and re@ approves.

kernel build. This makes it possible for me not to get pissed off that
random.ko crashes the system trying to rdtsc() when the i386/cpu.h
support code decides it's okay to call that op when neither I386_CPU or
I486_CPU is defined. I guess it also makes WITNESS/INVARIANTS defines
get picked up by the modules.
no matter where in the directory structure it may be. Use this and the "-k"
flag in the generated gdbinit files so that the "getsyms" function in gdb
requires no user intervention to run and will find every module if they're
in the kernel build's module directory. This is still quite useful for
cases where gdb knows that the path for some modules is /boot/kernel and
others are in the object directory for /usr/src/sys/$ARCH/compile/kernel.

Always use sys/conf/kern.mk when building kernel/modules.
<bsd.kern.mk> is only preserved for sys/boot/pc98/boot2
for now, but this will be fixed. If there are other
users of <bsd.kern.mk>, please let me know.
