Routine Description:
The following routine asks either Cc or Mm to get rid of any cached
pages on a file. Note that this will fail if a user has mapped a file.
If there is a shared cache map, purge the cache section. Otherwise
we have to go and ask Mm to blow away the section.
NOTE: This caller MUST own the Vcb exclusive.
Arguments:
Fcb - Supplies a pointer to an fcb
FlushType - Specifies the kind of flushing to perform
Return Value:
None.
