Subject: [PATCH v4 0/2] sched/topology: Asymmetric topologies fixes
Date: Wed, 23 Oct 2019 16:37:43 +0100	[thread overview]
Message-ID: <20191023153745.19515-1-valentin.schneider@arm.com> (raw)

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
