yeah, the flamegraph scripts are the outliers, there, everything else is using /bin/bash, so I'll switch to that, ok Andreas?
Sure, no problem. Thanks!
Just a gentle reminder that this can still be fixed in today's linux-next tree (next-20200504).
Thanks for the reminder, I've just added this to my tree:

oops, make that this instead:
