minutes: IO Visor TSC/Dev Meeting

Brenden Blanco
 

Hi All,

Thanks for joining in to the discussion today. Below are my notes from
the call. Hope everyone is looking forward to good discussions at the
LPC BPF track in Vancouver in two weeks! Since that overlaps with the
usual IO Visor call, we will have our next meeting in 4 weeks time
instead.

Thanks,
Brenden
