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()
