H A Dhrtimers.rst2 hrtimers - subsystem for high-resolution kernel timers
5 This patch introduces a new subsystem for high-resolution kernel timers.
8 (kernel/timers.c), why do we need two timer subsystems? After a lot of

20 mess. The timers.c code is very "tightly coded" around jiffies and
27 high-res timers.
