+Subject: [PATCH] Change the location we include linux/xattr.h
+
+This header stuff seems a bit fragile, but Serge reports including
+it in sys/capability.h was causing a lot of trouble building dependent
+app packages.
+
+From the perspective of libcap, this API is only needed internally in
+cap_file.c so we put an include there.
+
+Status: upstream.
