Vince, does the below (untested) patch work for you?
yes, this patch fixes things for me.
Tested-by: Vince Weaver vincent.weaver@maine.edu
is this patch going to make it upstream? It's a fairly major correctness bug with perf_event_open().
I just sent it to Linus.
In hindsight this should have been marked Cc: stable for v5.4 - we should forward it to Greg once Linus has pulled it:
da9ec3d3dd0f: ("perf: Correctly handle failed perf_get_aux_event()")
Note that in the v5.4 cherry-pick there's a conflict due to interaction with another recent commit - I've attached the ported fix against v5.4, but have only test built it.
Thanks for the backport, now queued up.
