Chris Wilson a5af081d01 drm/i915/perf: Mark up the racy use of perf->exclusive_stream ... Inside the general i915_oa_init_reg_state() we avoid using the perf->mutex. However, we rely on perf->exclusive_stream being valid to access at that point, and for that we have to control the race with disabling perf. This relies on the disabling being a heavy barrier that inspects all active contexts, after marking the perf->exclusive_stream as not available. This should ensure that there are no more concurrent accesses to the perf->exclusive_stream as we destroy it. Mark up the races around the perf->exclusive_stream so that they stand out much more. (And hopefully we will be running kcsan to start validating that the only races we have are carefully controlled.)
