From: "Steven Rostedt (Red Hat)" Jungseok Lee noticed the following: Currently, row's width of 7-digit duration numbers not aligned with other cases like the following example. 3) $ 3999884 us | } 3) | finish_task_switch() { 3) 0.365 us | _raw_spin_unlock_irq(); 3) 3.333 us | } 3) $ 3999976 us | } 3) $ 3999979 us | } /* schedule */ As adding a single white space in case of 7-digit numbers, the format could be unified easily as follows. 3) $ 2237472 us | } 3) | finish_task_switch() { 3) 0.364 us | _raw_spin_unlock_irq(); 3) 3.125 us | } 3) $ 2237556 us | } 3) $ 2237559 us | } /* schedule */ Instead of making a special case for 7-digit numbers, the logic of the len and the space loop is slightly modified to make the two cases have the same format.
