Subject: [PATCH 1/2] ftrace: draw_funcgraph.py: Handle dots in function names
From: Alex Snast <alexsn@...ibm.com>
ftrace function tracer can output the following line:
mmcommon-3250 [001] 969103.003748: clear_buddies.isra.59 <-dequeue_task_fair
However the regex used by draw_functrace.py would fail to match the '.'
character
