Inconceivableable

I have no idea who created the name for PNP_DEVICE_NOT_DISABLEABLE, but I probably have the same reaction as you ... "seriously?  that is what they named?"  I mean come on, I think it could have at least been named PNP_DEVICE_CANNOT_BE_DISABLED.  I am sure you can think of some better names too. If so, please leave a comment with your suggestions!  While we had a chance to rectify this in KMDF in the WDF_DEVICE_STATE structure, we chose to keep the field name (NotDisableable) similar to the WDM name to avoid confusion.

For any readers who have not encountered this bit, it is a part of PNP_DEVICE_STATE.  You set this bit in the IRP_MJ_PNP/IRP_MN_QUERY_PNP_DEVICE_STATE IRP after calling IoInvalidateDeviceState.

    The issue was something I was aware of before Doron mentioned the word in Once not disableable, forever
