FSCTL_REQUEST_BATCH_OPLOCK issue

[mohammad galal]

Hi all,

while i was trying to test the dokan sharing capabilities i found that
while i marked the dokan driver as shared drive and tring to access it
through the network, the dokan log unknown FSCTL 1 and 2 which
accordingly are

# FSCTL_REQUEST_BATCH_OPLOCK
# FSCTL_OPLOCK_BREAK_ACKNOWLEDGE

and i found that these FSCTLs are the normal way that MS implement the
client-server's sharing access protocol using "opputinistic locks" or
Oplocks.

so now i think this may be a good features to implement, any how i
will try to make some effort in doing that,

any help or any ideas even about how complex this issue will be
appreciated

thanks
