[PATCH 06/13] perf tools: Use tid in mmap/mmap2 events to find maps

From: Arnaldo Carvalho de Melo
Date: Tue Mar 18 2014 - 17:26:30 EST


From: Don Zickus <dzickus@xxxxxxxxxx>

Now that we can properly synthesize threads system-wide, make sure the
mmap and mmap2 events use tids instead of pids to locate their maps.
