Shutdown sequence: NDIS and FSDs

NTDEV
1

Hi all,

we are developing a custom block device driver which will work over the
network and thus talks to the network layers from its bottom side.
My question is (for both NT4 and w2k OSes):

  • does the OS guarantee that NDIS layer will not be shut down before all
    FSDs will flush their caches?
    Otherwise, we will have problems if NDIS will be already shut down and
    we will not be able to process the cache flush at shutdown activity from the
    FSDs.

From what I can see here, until and unless I return all the packets and
flush my queues NDIS does not shutdown or let my driver unload.
If I have any queues that need to be flushed then I wait in my shutdown
handler until I have flushed them, and until my shutdown handler exits, NDIS
does not unload ( or so it seems ).

Ramit.
