Oh really? I always base my tracing patches against tip/master, assuming
tracing/ftrace is about always quickly merged into master.
But the opposite is not necessarily true, I guess you don't merge master
into tracing/ftrace so quickly to not break the history right? And I guess
it's better to catch bugs if each individual topics is not too quickly synced
against tip/master.
