Merge branch 'tracing-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip
* 'tracing-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: tracing: Remove comparing of NULL to va_list in trace_array_vprintk() tracing: Fix function graph trace_pipe to properly display failed entries tracing: Add full state to trace_seq tracing: Buffer the output of seq_file in case of filled buffer tracing: Only call pipe_close if pipe_close is defined tracing: Add pipe_close interface
