Peter Zijlstra 82aad7ff7a perf/hw_breakpoint: Annotate tsk->perf_event_mutex vs ctx->mutex ... Perf fuzzer gifted a lockdep splat: perf_event_init_context() mutex_lock(parent_ctx->mutex); (B) inherit_task_group() inherit_group() inherit_event() perf_event_alloc() perf_try_init_event() := hw_breakpoint_event_init() register_perf_hw_breakpoint() mutex_lock(child->perf_event_mutex); (A) Which is against the normal (documented) order. Now, this is a false positive in that child is not published yet, but also inherited events never end up on ->perf_event_list. Annotate this one away.
