warning C28150: The function causes the IRQ Level to be set above the maximum acceptable for the function being analyzed

Additional information

The level limits come from annotations on the current function.


The specified function has raised the IRQL above the maximum IRQL permitted for the current function call.

This warning occurs inside a function that has been annotated with the __drv_maxIRQL annotation and indicates either a coding error in the function or a misunderstanding of the function's contract in the annotations.
