Subject: [PATCH 0/6] perf: Various event scheduling improvements

Hi,

These patches bring (I hope) a bit more scalability and fairness
to the perf events scheduling.

But this is only an introduction as there is still some work to
do, like ensuring all pinned events have been scheduled before
flexible ones (for now we schedule in order cpu pinned, cpu flexible,
task pinned, task flexible), among other improvements.


Frederic Weisbecker (6):
  perf/core: Split context's event group list into pinned and non-pinned lists
  list: Introduce list_rotate_left()
  perf: Round robin groups of events using list_rotate_left()
  perf: Export software-only event group characteristic as a flag
  perf: Don't rotate pinned groups
  perf: Increase round-robin fairness of flexible events
