[Qemu-devel] [PULL 09/16] cleanup-trace-events.pl: Tighten search for trace event call

[Stefan Hajnoczi <stefanha@redhat.com>]

From: Markus Armbruster <armbru@redhat.com>

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.
