Merge tag 'trace-fixes-v3.9-rc-v3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull ftrace fixes from Steven Rostedt: "Namhyung Kim found and fixed a bug that can crash the kernel by simply doing: echo 1234 | tee -a /sys/kernel/debug/tracing/set_ftrace_pid Luckily, this can only be done by root, but still is a nasty bug." * tag 'trace-fixes-v3.9-rc-v3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: ftrace: Move ftrace_filter_lseek out of CONFIG_DYNAMIC_FTRACE section tracing: Fix possible NULL pointer dereferences
