b40ce4165d KSE Milestone 2
Note ALL MODULES MUST BE RECOMPILED
make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

Sorry john! (your next MFC will be a doosie!)

7ca7bbb36b Simplify this a bit so that it doesn't have to generate silly redundant
__P() prototypes when an ansi-style static inline is a prototype already.
Since vnode_if.[ch] are generated on the fly, there are no CVS diffs to
mess up.

35b1da8080 remove crufty exec stuff, perl is in the base system
make it work with warnings on (there was some harmless use of uninitialized
variables)
make it work with 'use strict'

6f77b2defc Use a seperate -c and -h mode. The vnode_if.c file is compiled only into
the kernel while the vnode_if.h header is a bunch of inlines to call the
code that is in the kernel. Generating the .h file on the fly is kinda
bogus because it has to match the one compiled into the kernel.

IMHO we should have kern/vnode_if.c and sys/vnode_if.h committed in the
tree but that's another battle.

3176a7fe12 Update this to be able to output ASSERT_VOP_(UN)LOCKED() based on the
lock specifications in kern/vnode_if.src.  At present, this do not
distinguish between exclusive and shared locks, and the kernel is so full
of bugs in this area that running with auto-generation of assertions
enabled makes DEBUG_VFS_LOCKS totally useless for anybody that has used it
for anything prior to outputting automated assertions.  Due to this, I made
vnode_if.sh only output locking assertions if you have the environment
variable DEBUG_ALL_VFS_LOCKS set to "YES".  In order to actually use the
assertions, you need to also add "options DEBUG_VFS_LOCKS" to your kernel
config file.

f9c8cab591 Add a vnode argument to VOP_BWRITE to get rid of the last vnode
operator special case. Delete special case code from vnode_if.sh,
vnode_if.src, umap_vnops.c, and null_vnops.c.

4e61198e8f Make the vnode opv vector construction fully dynamic. Previously we
leaked memory on each unload and were limited to items referenced in
the kernel copy of vnode_if.c.  Now a kernel module is free to create
it's own VOP_FOO() routines and the rest of the system will happily
deal with it, including passthrough layers like union/umap/etc.

Have VFS_SET() call a common vfs_modevent() handler rather than
inline duplicating the common code all over the place.

Have VNODEOP_SET() have the vnodeops removed at unload time (assuming a
module) so that the vop_t ** vector is reclaimed.

Slightly adjust the vop_t ** vectors so that calling slot 0 is a panic
rather than a page fault.  This could happen if VOP_something() was called
without *any* handlers being present anywhere (including in vfs_default.c).
slot 1 becomes the default vector for the vnodeop table.

TODO: reclaim zones on unload (eg: nfs code)

fd5d1124e2 VOP_STRATEGY grows an (struct vnode *) argument
as the value in b_vp is often not really what you want.
(and needs to be frobbed). more cleanups will follow this.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

40560c4471 Don't #include vm stuff in vnode_if.[ch]. Enough vm stuff (a
single typedef) is now declared in <sys/types.h>.

This is the first of 4 commits that will remove some excessive
includes of vm*.h and user.h.  The total speed improvement isn't
as large as I first thought.  `make depend; make' for LINT only
improved from 2180 seconds to 2108 seconds user time.

5e3e8d2b88 Generate prototypes for VOP functions. I decided to keep the old-style
definitions even though the functions are inline.  If vnode_if.h was
compiled by a non-ANSI compiler, then `inline' would be defined away,
so vnode_if.h might compile correctly.

4777741358 Removed my special-case hack for VOP_LINK and fixed the problem with the
wrong vp's ops vector being used by changing the VOP_LINK's argument order.
The special-case hack doesn't go far enough and breaks the generic
bypass routine used in some non-leaf filesystems. Pointed out by Kirk
McKusick.

083c109df6 The generated VCALL always uses the first vp which in the case of /link/
might not be handled by the same FS as the directory (e.g. special device
files)...so it must be special-cased. This bug is seen when doing
"ln /dev/console /dev/foo" or equivilent and first appeared after I fixed
the argument order of VOP_LINK.  YUCK! There really needs to be a way of
specifying what vp to use in the VCALL; doing this could fix the strategy
and bwrite special-cases, too.
