• 4dc0da869   perf: Add context field to perf_event ... Browse Code »

  The perf_event overflow handler does not receive any caller-derived
  argument, so many callers need to resort to looking up the perf_event
  in their local data structure. This is ugly and doesn't scale if a
  single callback services many perf_events.

  Fix by adding a context parameter to perf_event_create_kernel_counter()
  (and derived hardware breakpoints APIs) and storing it in the perf_event.
  The field can be accessed from the callback as event->overflow_handler_context.
  All callers are updated.
