Pull tracing fixes from Steven Rostedt: "Oleg Nesterov found and fixed a bug in the perf/ftrace/uprobes code where running: # perf probe -x /lib/libc.so.6 syscall # echo 1 >> /sys/kernel/debug/tracing/events/probe_libc/enable # perf record -e probe_libc:syscall whatever kills the uprobe. Along the way he found some other minor bugs and clean ups that he fixed up making it a total of 4 patches. Doing unrelated work, I found that the reading of the ftrace trace file disables all function tracer callbacks. This was fine when ftrace was the only user, but now that it's used by perf and kprobes, this is a bug where reading trace can disable kprobes and perf. A very unexpected side effect and should be fixed" * tag 'trace-fixes-v3.16-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Remove ftrace_stop/start() from reading the trace file tracing/uprobes: Fix the usage of uprobe_buffer_enable() in probe_event_enable() tracing/uprobes: Kill the bogus UPROBE_HANDLER_REMOVE code in uprobe_dispatcher() uprobes: Change unregister/apply to WARN() if uprobe/consumer is gone tracing/uprobes: Revert "Support mix of ftrace and perf"
