I've queued both already, yes, but for the first one you name I'm not
really intending to put it into 4.15 and 4.14 - this is the kind of
issue where older trees simply won't have fixed anymore. The problem
only affects an obscure configuration, which is hardly used anywhere
for real. Or are you suggesting that CI runs randconfig tests also
against branches which are in security-only mode? (If it does, then
I'm not sure this isn't a mistake, because issues not introduced by
security fixes wouldn't be fixed there anymore either.)
