Since I just merged v3 of the mentioned patch and I'm wrapping the PR
for Linus, the above scared me more than a bit.

AFAICS the issue reported here is the  unconditional 'fi' dereference
spotted and fixed during code review, so no real problem after all.
Correct. Jakub spotted the error, it was fixed in a v2 5 days ago, and has since
been superceded by Oscar's patch, so nothing to worry about.

Is there a way to indicate to bots not to check superceded patches. In this case
I'd have though my v2 would have been a signal? Is there something else I should
have done?
sorry for this. our bot failed to recognize the mail structure to spot out the
v2 patch.

we'll consider how to improve it or be more careful while manual check. sorry
for inconvience caused.
Brett
