"unknown ioctl 0x731a" error during boot

[littlejackal]

Description

• during system boot, nvme driver reports "unknown ioctl 0x731a" error
• this error does not repeat, does not appear to affect functionality of the system or inhibit the operation of the system in any way
• reporting this as an 'informational' rather than 'breaking' issue

Steps to Reproduce

• autoconf kernel with nvme driver built in
• reboot system
• observe boot messages

Expected Behavior

• presumably driver should respond to ioctl 0x731a in some manner

Actual Behavior

• driver does not, and reports as such
