Re: [ros-diffs] [mjmartin] 41269: - IopCreateDriver: Change MajorFunction routines back to internal function IopInvalidDeviceRequest for ones that were set to NULL in the Drivers DriverEntry. Windows does it and so shall we.

[Alex Ionescu]

I must say that I protest to all the recent I/O changes, and in my
opinion, they are all wrong and badly researched, and have hacked what
was once good code.

Best regards,
Alex Ionescu
