+From c463b51e8ea1ae47a7bb8cc2777eb550ad3273e2 Mon Sep 17 00:00:00 2001
+From: Andreas Gruenbacher <agruenba@redhat.com>

+Subject: [PATCH] posix_acl: Add set_posix_acl
+
+Factor out part of posix_acl_xattr_set into a common function that takes
+a posix_acl, which nfsd can also call.
+
+The prototype already exists in include/linux/posix_acl.h.
