Subject: simpletrace: fix process() argument count
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d8e8ef4ee05bfee0df84e2665d9196c4a954c095;p=qemu.git

simpletrace: fix process() argument count

The simpletrace.process() function invokes analyzer methods with the
wrong number of arguments if a timestamp should be included.  This patch
fixes the issue so that trace analysis scripts can make use of
timestamps.
