There was no warning if a bad trace event name was given to 'trace-event' command, thus the user could think that the command was successful even if this was not the case. Print a warning if the user tries to enable a trace event which is not known. Acked-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
