The patch titled Add better resolution to initcall_debug timings has been removed from the -mm tree. Its filename was add-better-resolution-to-initcall_debug-timings.patch This patch was dropped because I dumped it on Ingo The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: Add better resolution to initcall_debug timings From: Tim Bird <tim.bird@xxxxxxxxxxx> Change the time resolution for initcall_debug to microseconds, from milliseconds. This is handy to determine which initcalls you want to work on for faster booting. One one of my test machines, over 90% of the initcalls are less than a millisecond and (without this patch) these are all reported as 0 msecs. Working on the 900 us ones is more important than the 4 us ones. With 'quiet' on the kernel command line, this adds no significant overhead to kernel boot time.
