Volume Filter Notification after chkdsk.

Hi all;
I have a volume level filter driver, i need a notification as to when
its ok to access the filesystem. .i.e after chkdsk. Currently the volume
filter open the files in IoRegisterBootDriverReinitialization(), this is
before chkdsk. Opening a file on the volume wont allow chkdsk to operate and
it BugChecks with SESSION_INITIALIZATION_FAILED.

Thanks & Regards
Faraz.
