| |
Hello, Ingo.
Can you please pull from the following git tree into sched/core to receive cpuhog patches?
git://git.kernel.org/pub/scm/linux/kernel/git/tj/misc.git cpuhog
Both sched/core and the patches remained the same from the second take[2]. Rusty Russell acked stop_machine changes and Oleg likes the changes.
Peter agrees with the mechanics but is unhappy with the naming and suggests using stop_cpu/machine() names instead. Currently, visible API is
* hog_one_cpu() * hog_cpus() * [__]stop_machine()
IIUC, Peter is suggesting something like (please feel free to correct if I got it wrong)
* stop_one_cpu() * stop_cpus() * [__]stop_machine()
The renaming shouldn't be difficult one way or the other but I think hog is better because it better describes what the API does (it doesn't really stop the cpu or cpus). Please refer to the discussions in the first take[1] and second take[2] for details.
The branch contains the following changes.
Tejun Heo (4): cpuhog: implement cpuhog stop_machine: reimplement using cpuhog scheduler: replace migration_thread with cpuhog scheduler: kill paranoia check in synchronize_sched_expedited()
