[PATCH v4 0/2] sched/topology: Asymmetric topologies fixes

From: Valentin Schneider
Date: Wed Oct 23 2019 - 11:38:48 EST


Hi,

I got a nice splat while testing out the toggling of
sched_asym_cpucapacity, so this is a cpuset fix plus a topology 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)

v4 changes:
- Patch 1/2: Directly tweak the cpuset array (Dietmar)
- Patch 2/2: Add an example to the changelog (Dietmar)

Cheers,
Valentin
