I am a new user to spdk, I trapped in some confusing warnings recently.
This one is about "Requested device XXX cannot be used" printed at the
end of spdk/example/nvm/perf/perf execution. That seems to tell me: hey,
your device doesn't work with spdk... yes, even though you've got the
perf results, but you'd better not trust it!
After investigating the source code, I understand the last print of this
warning appears when spdk releases resources after all work is done. So
I suppose it should say something like "we are finishing using this
device" instead. What do you think?
I also put this on github issues page
), but still think I can collect
more ideas from the mailing list.
All the best!
