More info for verboseboot message
I found this in my logs:
zfs kernel: ENOMEM 0xfffff80217394000 on 0xfffff80007881600(ada0)
Which turns out to be a verboseboot message, which seems to about something that does no harm.
I suggest to add atleast the filename to the message.

Correct attachement, use __FILE__ instead of __file__
