+Subject: [PATCH 34/54] Smack: fix behavior of smack_inode_listsecurity
+
+Security operation ->inode_listsecurity is used for generating list of
+available extended attributes for syscall listxattr. Currently it's used
+only in nfs4 or if filesystem doesn't provide i_op->listxattr.
+
+The list is the set of NULL-terminated names, one after the other.
+This method must include zero byte at the and into result.
+
+Also this function must return length even if string does not fit into
+output buffer or it is NULL, see similar method in selinux and man listxattr.
