  changes since v3 (per James):
- change to return with existing value -ENOMEM
- split doc part to a separate patch since they are going to be merged through
  separate trees.

changes since v2:
- remove unnecessary overflow check (per Peter)

changes since v1:
- drop out patch2 because it has been fixed on upstream (Thanks James for reminding)
- move sanity check into rb_alloc_aux (per Leo)
- add overflow check (per James)

Shuai Xue (2):
  perf/core: Bail out early if the request AUX area is out of bound
