Subject: [PATCH 02/10] xfrm: policy: use hlist rcu variants on inexact insert, part 2
From: Florian Westphal <fw@...len.de>
This function was modeled on the 'exact' insert one, which did not use
the rcu variant either.
When I fixed the 'exact' insert I forgot to propagate this to my
development tree, so the inexact variant retained the bug.
Fixes: 9cf545ebd591d ("xfrm: policy: store inexact policies in a tree ordered by destination address")
