This is evidently from the backport of

351652421e41 ("xfs: remove unnecessary dirty bli format check for ordered bufs")

It was fixed upstream in

7bf7a193a90c ("xfs: fix compiler warnings")

which contains a few other fixes as well. I have verified that all five
trivial changes in the fixup patch should be backported into v4.9-stable
as well.

> 4 net/ipv6/route.c:1270:6: warning: 'rt_cookie' may be used uninitialized in this function [-Wmaybe-uninitialized]

Introduced in the backport of
c5cff8561d2d ("ipv6: add rcu grace period before freeing fib6_node")
Fixed in
3614364527da ("ipv6: Fix may be used uninitialized warning in rt6_check")

Please backport both fixups.
