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.
This is a good change but it cannot go yet because it is dependent on Jiri's
"perf tools: Share map groups within process" series.
No it isn't. :-) Commit bfd66cc71a3f831ba7c2116d79416cfb8883f6cf is the
reason why. It synthesizes thread events to make this work correctly.
ok, I haven't realized this one was pulled in as well ;-)
it's ok then..
No, you mustn't split up the maps between threads. We currently assume
CLONE_VM is always used to create threads.
But that doesn't work when you try to synthesize threads which was the
problem I was trying to solve.
