This is interesting. My mental model was that Linux is never going to have
LIST_FOREACH_SAFE, but DPDK will eventually gain its own polyfill. I was
actually expecting it to happen before my patch is published, so this was a
reminder to remove my own definition since it clearly belongs to some common
library. Turns out I was wrong on both accounts: there are Linuxes that define
LIST_FOREACH_SAFE, and I managed to submit faster. Apart from these
organizational issues the whole else branch can be safely removed. Do you want
me to submit an updated version?
