Re: Passive in arbitrary context?

and typically you don't sleep in the context, you pend the irp and do the
work later.

Dispatch routines of the topmost driver are running in the app's
thread,
the thread which called Read/WriteFile or DeviceIoControl.
PnP and Power dispatch routines are running in system thread context,
so
are any work items queued by ExQueueWorkItem.

Do some driver routines run in an arbitrary thread context even though
they're called at passive level? (as opposed to the context of the
user thread that requested them or some system thread) Does that mean
that whenever such a routine sleeps, it steals part of the quantum of
a thread that really doesn't care anything about it?
