[ofw] ***SPAM*** IoGetDeviceObjectPointer in H/W driver code

[Deepak Gupta]

Hi,

I see a call to IoGetDeviceObjectPointer in h/w driver code in the callback
registered for GUID_IB_CI_INTERFACE (callback is registered in IRP_MN_START
handler).

According to MSDN documentation "IoGetDeviceObjectPointer" should be called
in system thread context.

How are we making sure that callback is being called in system thread
context?
Are callbacks registered using "IoRegisterPlugPlayNotification" called in
system thread context?

Or is this some leftover in MSDN  from NT4/2k days

Can any one clarify on this?


Regards
Deepak
