Routine Description:
|
||||
|
||||
This routine handles the PnP surprise remove operation. This is another
|
||||
type of notification that the underlying storage device for the volume we
|
||||
have is gone, and is excellent indication that the volume will never reappear.
|
||||
The filesystem is responsible for initiation or completion the dismount.
|
||||
|
||||
For the most part, only "real" drivers care about the distinction of a
|
||||
surprise remove, which is a result of our noticing that a user (usually)
|
||||
physically reached into the machine and pulled something out.
|
||||
|
||||
Surprise will be followed by a Remove when all references have been shut down.
|
||||

||||
Arguments:

Irp - Supplies the Irp to process
