The patch titled printk time parameter has been removed from the -mm tree. Its filename is printk-time-parameter.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ Subject: printk time parameter From: Jan Engelhardt <jengelh@xxxxxxxxxxxxxxx> Currently, enabling/disabling printk timestamps is only possible through reboot (bootparam) or recompile. I normally do not run with timestamps (since syslog handles that in a good manner), but for measuring small kernel delays (e.g. irq probing - see parport thread) I needed subsecond precision, but then again, just for some minutes rather than all kernel messages to come. The following patch adds a module_param() with which the timestamps can be en-/disabled in a live system through /sys/modules/printk/parameters/printk_time.
