Split-up struct perf_event_context::group_list into pinned_groups and flexible_groups (non-pinned). This first appears to be useless as it duplicates various loops around the group list handlings. But it scales better in the fast-path in perf_sched_in(). We don't anymore iterate twice through the entire list to separate pinned and non-pinned scheduling. Instead we interate through two distinct lists. The another desired effect is that it makes easier to define distinct scheduling rules on both. Changes in v2: - Respectively rename pinned_grp_list and volatile_grp_list into pinned_groups and flexible_groups as per Ingo suggestion. - Various cleanups Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com> Acked-by: Peter Zijlstra <peterz@infradead.org> Cc: Paul Mackerras <paulus@samba.org> Cc: Ingo Molnar <mingo@elte.hu> Cc: Arnaldo Carvalho de Melo <acme@infradead.org> |
