I agree that the PQ/IOPF work in this patch overlaps with Tomasz's ATS/PRI/SVA series. Please consider this patch withdrawn. I will review his branch and coordinate any remaining work with him rather than duplicate the existing implementation. I also agree that the debugfs test helper should not be mixed with the core implementation. If I send follow-up work, I will keep the test helper in a separate patch. Regards, Bingyu
