Subject: Windows: Freelance whole volume rdr invalidate
X-Git-Tag: upstream/1.8.0_pre1^2~602

Windows: Freelance whole volume rdr invalidate

When updating the Freelance directory do not notify the redirector
of individual objects to invalidate since that can leaad to race
conditions.  Send whole volume invalidations since that is what is
required in any case.
