From f871d6893a7bf8c14db162f6e75a5f8157e4c2bb Mon Sep 17 00:00:00 2001 From: Blue Swirl Date: Wed, 13 Oct 2010 19:14:29 +0000 Subject: trace: print a warning if user tries to enable an unknown trace event 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.
