Routine Description:
The address of this routine is specified when creating a CacheMap for
a file. It is subsequently called by the Lazy Writer prior to its
performing closes to the file. This callback is necessary to
avoid deadlocks with the Lazy Writer. (Note that normal closes
acquire the Vcb, and then call the Cache Manager, who must acquire
some of his internal structures. If the Lazy Writer could not call
this routine first, and were to issue a write after locking Caching
data structures, then a deadlock could occur.)
Arguments:
Vcb - The Vcb which was specified as a close context parameter for this
routine.
Wait - TRUE if the caller is willing to block.
Return Value:
FALSE - if Wait was specified as FALSE and blocking would have
been required. The Fcb is not acquired.

Routine Description:
This routine is called to check if a volume is ready for dismount. This
occurs when only file system references are left on the volume.
If the dismount is not currently underway and the user reference count
has gone to zero then we can begin the dismount.
If the dismount is in progress and there are no references left on the
volume (we check the Vpb for outstanding references as well to catch
any create calls dispatched to the file system) then we can delete
the Vcb.
Arguments:
Vcb - Vcb for the volume to try to dismount.
Force - Whether we will force this volume to be dismounted.
Return Value:
BOOLEAN - True if the Vcb was not gone by the time this function finished,
False if it was deleted.
This is only a trustworthy indication to the caller if it had the vcb
exclusive itself.
