Repetitive IRP_MJ_QUERY_INFORMATION calls on root

NTFSD
1

I insert a floppy formated with my file system (WinXP), press start->run,
enter a:, hit return. My FSD is mounted on the empty volume, the root is
opened and queried. This all apears to work fine, then I get several
repeating attempts to open the root as a file and get FileBasicInformation
info on it. These calls come in one after another, and there are about 5.
I am concerned because FastFat never gets these requests, and I am having
more serious issues later on when creating directories. I would like to
resolve this peculiarity before tracking down problems that occur later. I
can post very detailed info if necessary, just tell me what to info to
provide. The FSD is in a very early stage of development (the filesystem
itself has been proven on several other platforms), and I have no prior NT
kernel mode driver experience.

Thanks in advance,
Jeremy

Be sure you will the output buffer for MN_QUERY_DIRECTORY correctly. See
FastFat source for details.
