a2721a0f1b In vfs_shutdown(), do the "sync and wait for it to finish" _before_
unmounting all of the file systems.  If we encounter a condition where
all of the dirty buffers could not flush, then don't unmount file systems,
since it might be likely to wedge.

4ad51c2811 Allow multiple export requests for a filesystem, host pair if the flags and
anon cred are the same. Should probably be handled better in the mountd,
but this will do for now. Fixes PR 469, submitted Sept 1994 by
a certain "Jason R. Thorpe".. ;-)

4702f17abc Add functions to set/reset the info about the publicly exported
(WebNFS) filesystem. At first glance this should go into the
NFS code, but all the other export code is here as well.

21bbd49bf2 in vfs_shutdown(), print "syncing disks... " before dropping to spl0(),
so that if the drop to spl0() causes another panic (e.g. because there's
still some fatal hardware interrupt that's pending) we'll know that we
dropped IPL to sync the disks.

e3f99a9397 Pass the vnode type to vaccess(), and use it when checking VEXEC. Make sure
that the mode bits passed to vaccess() and returned by foo_getattr() contain
only permission bits.

8f5978a181 GC VS[UG]ID and VSVTX, and add a new VLOOKUP, since the semantics are now
different from VEXEC.

6911ff7d13 Fix two performance issues:
* When a delayed write buffer falls off the LRU queue, arrange for it to go on
  the AGE queue after being flushed out to disk.
* When a delayed write buffer is synced, leave it in its relative position in
  the LRU queue.

0538233e2c Implement changes to make fix for NQNFS and MFS unmounting (race conditions)
work. Not quite as good as with the Lite2 merges, but it'll do until then.

* dounmount() expects to be called with the mountpoint marked busy
* all callers of dounmount() thus make the call themselves
* if a filesystem was being unmounted, and we're woken up in vfs_busy(),
  don't reference the mountpoint struct pointer, as it has very probably
  been freed.

68de7ca719 - Implement vfs_mountroot(). This function is called my main() to
mount the root file system.  If the operator specified the root
  file system type in the kernel configuration file, attempt to
  mount that file system type on the root device.  If the root
  file system type was wildcarded (or unspecified), try all of
  the file systems statically built into the kernel until one
  succeeds.  If no file systems succeed, return an error.  The
  system will recover from this condition.
- Implement vfs_getopsbyname().  This function returns the file
  system ops vector given a file system name.

60b9a20b61 initialize vnode_free_list and mountlist at compile time with the new
queue.h list/queue head initializer macros.  mountlist was converted so
that panics (or other reboots) early on in kernel startup don't cause
sys_sync() to croak.  vnode_free_list was converted because it was nearby.
