+Subject: [PATCH] tmpfiles: avoid null free() for acl attributes
+
+When built with ACL support, we might be processing a tmpfiles
+entry where there's no cause for us to call parse_acls_from_arg,
+then we get to the end of parse_line without having ever populated
+i.{acl_access, acl_default}.
+
+Then we pass a null pointer into acl_free().
+

+Subject: [PATCH] nspawn: guard acl_free() with a NULL check
+
+Inspired by #25957 there's one other place where we don't guard
+acl_free() calls with a NULL check.
+
+Fix that.
