Hello, all.
cpu_hog has been renamed to cpu_stop and moved into kernel/stop_machine.c per Peter Zijlstra's suggestion. This patchset is feature-wise identical to the second take of cpuhog[L]. The only changes are the rename, relocation and refresh against the current sched/core.
The following API renames took place.
- hog_one_cpu() -> stop_one_cpu() - hog_one_cpu_nowait() -> stop_one_cpu_nowait() - hog_cpus() -> stop_cpus() - try_hog_cpus() -> try_stop_cpus() - *_hog() callbacks -> *_cpu_stop()
Internal names have been renamed accordingly. e.g. cpuhog thread became cpu_stopper thread and so on.
This patchset contains the following four patches.
0001-cpu_stop-implement-stop_cpu-s.patch 0002-stop_machine-reimplement-using-cpu_stop.patch 0003-scheduler-replace-migration_thread-with-cpu_stop.patch 0004-scheduler-kill-paranoia-check-in-synchronize_sched_e.patch
The patches are against the current linux-2.6-tip/sched/core (09a40af5240de02d848247ab82440ad75b31ab11) and are available in the following git tree.
git://git.kernel.org/pub/scm/linux/kernel/git/tj/misc.git cpu_stop
I retained the original acked/reviewed-by's as the changes are mostly cosmetic. If you disagree, please let me know. I'll try to push this through sched/core again once Peter acks.
diffstat follows.
