make lost-tick detection more informative
Quoted 5 lines · Andrew Morton
I've actually disabled it in -mmnext, because I get too much mail already.
If you want to slap this on top of that and some new kernel-hacking debug config option, that would be neat.
On x86-64/2.4 it is a kernel option "report_lost_ticks"
The overhead is low (single if check in the timer handler), so this is fine.
If you suspect something goes wrong due to bad latency you can just tell the user to turn it on.
