Afaik References: is for other reading (bug reports, discussions, other patch series), Link: is for patch submission itself (which I think some subsystem do an entire chain of, on each revision). My scripts aren't good enough that they add the Link: before submitting, I add them when I apply patches (since most patches I get don't have them anyway). btw since the final patch to remove follow_pfn won't be ready for 5.12 merge window (kvm and vfio have some work to do) I think it's best if you just queue this up in your tree?
