However despite me being a smart arse in the commit message it's actually not correct. In particular it interacts badly with a global perf record. We will have to do something more complicated, but that will have to wait for 3.11. Signed-off-by: Michael Ellerman Signed-off-by: Benjamin Herrenschmidt --- Reading git-diff-tree failed
