How does IO manager notifies a failed lock

NTDEV
1

When issuing an IRP with a direct IO method
and the IO manager cannot perform the lock
to physical memory, does that IRP get to the driver ?
What is the error code the user is notified with ?

The IRP will not make it to the driver. I don't know the exact status
without checking the source, but i'd guess it's the win32 equivalent of
the NT status code STATUS_INSUFFICIENT_RESOURCES.

In my experience, the error returned by DeviceIoControl is ERROR_NOACCESS.
