We are talking about two different things here. One is the Linux NVMe host code that can be used with lots of different controllers. Many of them are PCIe controller, especially cheap ones. The other is the Linux NVMe target code. So if a fix for very common PCIe controller trigger a bug in the target code there is no 1:1 relationship as even if you are talking to a Linux fabrics controller it usually runs a different kernel version on a different system. That being said you can always backport that fix as well, which probably is a good idea as it fixes a real bug. Nevermind that nothing in your revert patch indicated it wasn't for mainline.
