Don't reset ->total_link_count on nested calls of vfs_path_lookup() we already zero it on outermost set_nameidata(), so initialization in path_init() is pointless and wrong. The same DoS exists on pre-4.2 kernels, but there a slightly different fix will be needed. Cc: stable@vger.kernel.org # v4.2 Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
