743312367a VFS_STATFS(mp, ...) is mostly called with &mp->mnt_stat, but a few cases
doesn't.  Most of the implementations have grown weeds for this so they
copy some fields from mnt_stat if the passed argument isn't that.

Fix this the cleaner way:  Always call the implementation on mnt_stat
and copy that in toto to the VFS_STATFS argument if different.

aec0fb7b40 Back when VOP_* was introduced, we did not have new-style struct
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)

5e8c582ac2 Put a version element in the VFS filesystem configuration structure
and refuse initializing filesystems with a wrong version.  This will
aid maintenance activites on the 5-stable branch.

s/vfs_mount/vfs_omount/

s/vfs_nmount/vfs_mount/

Name our filesystems mount function consistently.

Eliminate the namiedata argument to both vfs_mount and vfs_omount.
It was originally there to save stack space.  A few places abused
it to get hold of some credentials to pass around.  Effectively
it is unused.

Reorganize the root filesystem selection code.

56f21b9d74 Rename suser_cred()'s PRISON_ROOT flag to SUSER_ALLOWJAIL. This is
somewhat clearer, but more importantly allows for a consistent naming
scheme for suser_cred flags.

The old name is still defined, but will be removed in a few days (unless I
hear any complaints...)

5a32489377 Make vm_page's PG_ZERO flag immutable between the time of the page's
allocation and deallocation.  This flag's principal use is shortly after
allocation.  For such cases, clearing the flag is pointless.  The only
unusual use of PG_ZERO is in vfs_bio_clrbuf().  However, allocbuf() never
requests a prezeroed page.  So, vfs_bio_clrbuf() never sees a prezeroed
page.

b4484bf031 Fixes problems that occurred when a file was removed and a directory
created with the same name, and vice versa:
- Immediately recycle vnodes of files & directories that have been deleted
or renamed.
- When looking an entry in the VFS name cache or smbfs's private
cache, make sure the vnode type is consistent with the type of file
the server thinks it is, and re-create the vnode if it isn't.

The alternative to this is to recycle vnodes unconditionally when their
use count drops to 0, but this would make all the caching we do
mostly useless.

91d5354a2c Locking for the per-process resource limits structure.
- struct plimit includes a mutex to protect a reference count.  The plimit
  structure is treated similarly to struct ucred in that is is always copy
  on write, so having a reference to a structure is sufficient to read from
  it without needing a further lock.
- The proc lock protects the p_limit pointer and must be held while reading
  limits from a process to keep the limit structure from changing out from
  under you while reading from it.
- Various global limits that are ints are not protected by a lock since
  int writes are atomic on all the archs we support and thus a lock
  wouldn't buy us anything.
- All accesses to individual resource limits from a process are abstracted
  behind a simple lim_rlimit(), lim_max(), and lim_cur() API that return
  either an rlimit, or the current or max individual limit of the specified
  resource from a process.
- dosetrlimit() was renamed to kern_setrlimit() to match existing style of
  other similar syscall helper functions.
- The alpha OSF/1 compat layer no longer calls getrlimit() and setrlimit()
  (it didn't used the stackgap when it should have) but uses lim_rlimit()
  and kern_setrlimit() instead.
- The svr4 compat no longer uses the stackgap for resource limits calls,
  but uses lim_rlimit() and kern_setrlimit() instead.
- The ibcs2 compat no longer uses the stackgap for resource limits.  It
  also no longer uses the stackgap for accessing sysctl's for the
  ibcs2_sysconf() syscall but uses kernel_sysctl() instead.  As a result,
  ibcs2_sysconf() no longer needs Giant.
- The p_rlimit macro no longer exists.

8b5905a47d - Remove the backtrace() call from the *_vinvalbuf() functions. Thanks to a
stack trace supplied by phk, I now understand what's going on here.  The
   check for VI_XLOCK stops us from calling vinvalbuf once the vnode has been
   partially torn down in vclean().  It is not clear that this would cause
   a problem.  Document this in nfs_bio.c, which is where the other two
   filesystems copied this code from.

ce1fb23146 - Remove interlock protection around VI_XLOCK. The interlock is not
sufficient to guarantee that this race is not hit.  The XLOCK will likely
   have to be redesigned due to the way reference counting and mutexes work
   in FreeBSD.  We currently can not be guaranteed that xlock was not set
   and cleared while we were blocked on the interlock while waiting to check
   for XLOCK.  This would lead us to reference a vnode which was not the
   vnode we requested.
 - Add a backtrace() call inside of INVARIANTS in the hopes of finding out if
   this condition is ever hit.  It should not, since we should be retaining
   a reference to the vnode in these cases.  The reference would be sufficient
   to block recycling.

a8d43c90af Add a "int fd" argument to VOP_OPEN() which in the future will
contain the filedescriptor number on opens from userland.

The index is used rather than a "struct file *" since it conveys a bit
more information, which may be useful to in particular fdescfs and /dev/fd/*

For now pass -1 all over the place.
