Hi,
The changes since v1 (https://lkml.org/lkml/2012/7/27/286) are:
- change naming from "user hooks" to "code domain tracking". - use of __this_cpu_* APIs instead of __get_cpu_*
There is still a dependency against Paul's rcu/idle branch and the vtime consolidation set: https://lkml.org/lkml/2012/6/19/216
Bold warriors can pull from:
