Ingo, Thomas,
Those are two fixes for the function graph tracer for .31
The first one fixes a possible race condition between a function graph trace reader and ring buffer writers, leading to a mixup inside an event entry, or worst.
The second one fixes some issues in the output of the function graph tracer while using splice on the trace_pipe file or ftrace_dump().
Both fixes should also be backported on .30 for the -stable branch.
Thanks, Frederic.
The following changes since commit 4733fd328f14280900435d9dbae1487d110a4d56: Benjamin Herrenschmidt (1): mm: Remove duplicate definitions in MIPS and SH

Lai Jiangshan (2): tracing: Fix invalid function_graph entry tracing: Fix missing function_graph events when we splice_read from trace_pipe
