It seems to depend on:

commit 4c355cdfbba537971b5c3849680b1b6453a7a383
Author: Reshetova, Elena <elena.reshetova@intel.com>
Date:   Tue Mar 21 13:59:19 2017 +0200

    net: convert sk_filter.refcnt from atomic_t to refcount_t

That split up sk_filter_charge() so that the refcount initialisation
won't trip the increment-from-zero check.
