> Thanks for reporting the dereference.  Could you provide a little more detail on how you created this issue?  Are you just running the two commands (ip, sriov_numvfs) in some rc script and if you put a few second sleep in front of it you don't see the failure?

Your understanding is correct; a rc script is run with ip and echo in
numvfs commands. I tried to reduce it to the minimum. If I put a sleep
20 in front of it, it does not crash. I also forgot to add I did not
had the issue in 3.14.x with the same script.

Best,
