We have a use case where the host is very minimal (like an embedded device)
and does not even have networking enabled. But it does have vsockets. We
need to trace this host and have it send its data to the guest. By running
trace-cmd listen on the guest and have the host use vsockets instead of
networking, can allow this host to be traced.


Steven Rostedt (Google) (4):
  trace-cmd listen: Remove UDP from function names
  trace-cmd listen: Replace bool use_tcp with enum type
  trace-cmd record: Replace bool use_tcp with enum type
  trace-cmd listen: Add vsocket usage
