This commit was manufactured to restore the state of the 6.0-RELEASE image.

UFS by:
- Making the pre and post hooks for the VOP functions work even when
DEBUG_VFS_LOCKS is not defined.
- Moving the KNOTE activations into the corresponding VOP hooks.
- Creating a MNTK_NOKNOTE flag for the mnt_kern_flag field of struct
mount that permits filesystems to disable the new behavior.
- Creating a default VOP_KQFILTER function: vfs_kqfilter()
My benchmarks have not revealed any performance degradation.

Add VOP_FOO_APV() which takes a pointer to the vop_vector.2005-02-08T12:54:32ZPoul-Henning Kampphk@FreeBSD.org2005-02-08T12:54:32Zurn:sha1:119798b384036a071be8217d107a8b4c23f22bd8
This allows stacked or partitioned filesystems to say "Continue
the normal resolution from here", for instace from FFS to UFS.
Use VNASSERT() instead of KASSERT().
Get rid of the VDESC() macro while the pot is boiling anyway, it is2005-01-13T08:05:20ZPoul-Henning Kampphk@FreeBSD.org2005-01-13T08:05:20Zurn:sha1:de8a6c067a98fe415c583676fe1e97408f2f36b7
only used from generate files now, so we might as well generate the
right stuff from the start.
Change the generated VOP_ macro implementations to improve type checking2005-01-13T07:53:01ZPoul-Henning Kampphk@FreeBSD.org2005-01-13T07:53:01Zurn:sha1:63f89abf4a49d64f983e3fed54e99633f0c70d57
and KASSERT coverage.
After this check there is only one "nasty" cast in this code but there
is a KASSERT to protect against the wrong argument structure behind
that cast.
Un-inlining the meat of VOP_FOO() saves 35kB of text segment on a typical
kernel with no change in performance.
We also now run the checking and tracing on VOP's which have been layered
by nullfs, umapfs, deadfs or unionfs.
Add new (non-inline) VOP_FOO_AP() functions which take a "struct
foo_args" argument and does everything the VOP_FOO() macros
used to do with checks and debugging code.
Add KASSERT to VOP_FOO_AP() check for argument type being
correct.
Slim down VOP_FOO() inline functions to just stuff arguments
into the struct foo_args and call VOP_FOO_AP().
Put function pointer to VOP_FOO_AP() into vop_foo_desc structure
and make VCALL() use it instead of the current offsetoff() hack.
Retire vcall() which implemented the offsetoff()
Make deadfs and unionfs use VOP_FOO_AP() calls instead of
VCALL(), we know which specific call we want already.
Remove unneeded arguments to VCALL() in nullfs and umapfs bypass
functions.
Remove unused vdesc_offset and VOFFSET().
Generally improve style/readability of the generated code.

do things correctly from an aliasing perspective. Put the
vop_generic_args element as the first element for all the vop_*_args
and adjust the code to take the address of that instead of the
structure.
OK'd based on a vague description by: phk
Cast from the specific vop_*_args to vop_generic_args via a (void *)2004-12-13T06:13:52ZWarner Loshimp@FreeBSD.org2004-12-13T06:13:52Zurn:sha1:98a67cd84080bb90ac5d8653ad473ca03e63965f

the moment.
# Chances are good that all the struct vop_*_args should have, as its
# first element, the struct vop_generic_args, and when necessary to

Back when VOP_* was introduced, we did not have new-style struct2004-12-01T23:16:38ZPoul-Henning Kampphk@FreeBSD.org2004-12-01T23:16:38Zurn:sha1:aec0fb7b40e4cf877bea663f2d86dd07c3524fe8
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)
