SubjectRe: linux-next build error (3)
From
Date
Dmitry,

Can you temporarily disable config options which are causing this build error?
syzbot is failing to test next-20180723 and next-20180724 due to this problem.

By the way, ".config" at
https://syzkaller.appspot.com/bug?id=bd788040e839b85be53a030f219a2a1e4dc8acd2 is
failing because of empty link.

<a href="">.config</a>
