You know, in the three or four names this thing has had, I'm not sure
if "exit" has ever appeared :D
It is accurate, which is a definite plus. But since the exit in
question is special due to accompanying EFAULT, I think we've been
trying to reflect that in the nomenclature ("memory faults" or
"userfault")- maybe that's not worth doing though.
Wrt the current name, I agree w/ you on the potential for userfaultfd
confusion but I sort of see Sean's argument as well [1]. I see you've
re-raised the question of the exit accompanying EFAULT in [2] though,
so we should probably resolve that first.
