System hangs or killed rcutorture guest OSes can result in truncated "Reader Pipe:" lines, which can in turn result in false-positive reader-batch near-miss warnings. This commit therefore adjusts the reader-batch checks to account for possible line truncation. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
