[PATCH v3 0/2] sched/topology: Asymmetric topologies fixes

From: Valentin Schneider
Date: Tue Oct 15 2019 - 11:46:55 EST


I got a nice splat while testing out the toggling of
sched_asym_cpucapacity, so this gets a new patch.

Details are in the logs.

v2 changes:
- Use static_branch_{inc,dec} rather than enable/disable

v3 changes:
- New patch: add fix for empty cpumap in sched domain rebuild
- Move static_branch_dec outside of RCU read-side section (Quentin)


Valentin Schneider (2):
sched/topology: Don't try to build empty sched domains
sched/topology: Allow sched_asym_cpucapacity to be disabled
