The patch below was submitted to be applied to the 4.13-stable tree.
I fail to see how this patch meets the stable kernel rules as found at
Documentation/process/stable-kernel-rules.rst.
I could be totally wrong, and if so, please respond to
<stable@xxxxxxxxxxxxxxx> and let me know why this patch should be
applied. Otherwise, it is now dropped from my patch queues, never to be
seen again.
thanks,

Subject: [PATCH] seccomp: make function __get_seccomp_filter static
The function __get_seccomp_filter is local to the source and does
not need to be in global scope, so make it static.
Cleans up sparse warning:
symbol '__get_seccomp_filter' was not declared. Should it be static?
