2014-09-26cleanup-trace-events.pl: Tighten search for trace event callMarkus Armbruster
The script can get fooled too easily. For instance, it finds trace_megasas_io_read_start when looking for trace_megasas_io_read, and incorrectly concludes that event megasas_io_read is used. Supply -w to git-grep to tighten the search.
