Yes, certainly — we can check with the disk vendor for updated firmware that correctly reports
NAWUPF. I’ve already discussed this with my manager, and he’ll arrange a call with the vendor
so that I can directly explain the issue and what we want from the kernel perspective.
I’ll follow up with you once I’ve spoken to the vendor.
