Hello,

I am trying to bisect a pktgen related performance regression that appears to
be between the 4.13 and 4.14 kernels.  But, my system keeps crashing due to part_in_flight
oops so bisecting is not going well.

It looks like this oops was fixed, but the link to the patch in the email is no longer
valid.  Can someone let me know what patch fixes this crash so I can apply it while
bisecting?

https://www.spinics.net/lists/linux-block/msg17809.html

Thanks,
Ben
