[RFC PATCH 0/1] perf/core: Wake up parent event if inherited event has no ring buffer

[James Clark]

This is one possible fix to the issue described in the commit message.

What I'm not sure about is whether these other two possibilities should
be done instead, which is what I'm looking for feedback on:

 * Assign the ring buffer of the parent event to the child in inherit_event()

 * Move the poll list from the RB to the event, although it was moved into
   the RB for a specific reason in 10c6db1
