| |
For some reason find_pmu_context is defined as returning void* rather than a __percpu struct perf_cpu_context*. As all the requisite types are defined in advance there's no reason to keep it that way.
This patch modifies the prototype of pmu_find_context to return a __percpu struct perf_cpu_context*.
