File 0158-9pfs-local-move-xattr-security-ops-.patch of Package qemu-testsuite.19799

From: Greg Kurz <groug@kaod.org>
Date: Sun, 26 Feb 2017 23:41:40 +0100
Subject: 9pfs: local: move xattr security ops to 9p-xattr.c

These functions are always called indirectly. It really doesn't make sense
for them to sit in a header file.

Signed-off-by: Greg Kurz <groug@kaod.org>
Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com>
(cherry picked from commit 56fc494bdcba35d74da27e1d34dbb6db6fa7bd67)
[BR: Fix and/or infrastructure for BSC#1020427 CVE-2016-9602]
