f257b7a54b Make VFS_ROOT() and vflush() take a thread argument.
This is to allow filesystems to decide based on the passed thread
which vnode to return.
Several filesystems used curthread, they now use the passed thread.

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!)

3157714de7 o Move from Alfred Perstein's "exclusion" technique of handling special
file types to requiring all file types to properly implement fo_stat.
  This makes any new file type additions much easier as this code no
  longer has to be modified to accomodate it.

o Instead of using curproc in fdesc_allocvp, pass a `struct proc' pointer as
  a new fifth parameter.

908a81d424 - Do not allow VOP_SETATTR to modify underlying vnodes at all. This caused
problems when fetch(1) was passed `-o -'.  The rationale of this change
  is that applications attempting to change underlying vnodes for /dev/fd
  nodes are improperly written and the use of this interface should not
  ever have been encouraged.  Proper alternatives are fchmod, fchown and
  others.

  PR:		18952

- Remove stale, unused fdescnode->fd_link structure member.

It was not discussed and should probably not happen.

740a1973a6 Change the way that the queue(3) structures are declared; don't assume that
the type argument to *_HEAD and *_ENTRY is a struct.

38edb6a32f Adapt fdesc to be mounted on /dev/fd and remove fd, stdin, stdout and
stderr nodes.  More specific items of this patch:
  o Removed support for symbolic links, and the need for
    fdesc_readlink().
  o Put all the code from fdesc_attr() into fdesc_getattr() and removed
    fdesc_attr().  This also made it easier to properly give all nodes
    unique inode numbers.
  o The removal of all non-fd nodes allowed the removal of the fdesc_read(),
    fdesc_write(), and fdesc_ioctl() nodes, since we no longer have nodes
    that get special handling.
  o Correct the component name validity-checking in fdesc_lookup().  It
    previously detected the end of the string by checking for a terminating
    NUL, now it uses cnp->cn_namelen.
  o Handle kqueue files as FIFOs.  This is probably the closest file type
    to represent this type of file there is, and it is unfortunately not
    very representative of a kqueue.  Creation time is not supported by
    kqueue, so ctime, mtime and atime are all set to the current time when
    getattr() was called.
  o Also set st_[mca]time to the current time since there's no data in
    socket structures that can be used to fill this in (FIFOs).
  o Simplify fdesc_readdir() since it only has to report the numbered
    fd nodes.  Add `.' and `..' directory links as well.
  o Remove read bits from directories as they tend to confuse programs
    like tar(1).

c447342094 Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL"
is an application space macro and the applications are supposed to be free
to use it as they please (but cannot).  This is consistant with the other
BSD's who made this change quite some time ago.  More commits to come.

996c772f58 This is the kernel Lite/2 commit. There are some requisite userland
changes, so don't expect to be able to run the kernel as-is (very well)
without the appropriate Lite/2 userland changes.

The system boots and can mount UFS filesystems.

Untested: ext2fs, msdosfs, NFS
Known problems: Incorrect Berkeley ID strings in some files.
		Mount_std mounts will not work until the getfsent
		library routine is changed.

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.

f57e65478d Introduced a type `vop_t' for vnode operation functions and used
it 1138 times (:-() in casts and a few more times in declarations.
This change is null for the i386.

The type has to be `typedef int vop_t(void *)' and not `typedef
int vop_t()' because `gcc -Wstrict-prototypes' warns about the
latter.  Since vnode op functions are called with args of different
(struct pointer) types, neither of these function types is any use
for type checking of the arg, so it would be preferable not to use
the complete function type, especially since using the complete
type requires adding 1138 casts to avoid compiler warnings and
another 40+ casts to reverse the function pointer conversions before
calling the functions.
