Merge tag 'trace-3.11-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracing fixes and cleanups from Steven Rostedt: "This contains fixes, optimizations and some clean ups Some of the fixes need to go back to 3.10. They are minor, and deal mostly with incorrect ref counting in accessing event files. There was a couple of optimizations that should have perf perform a bit better when accessing trace events. And some various clean ups. Some of the clean ups are necessary to help in a fix to a theoretical race between opening a event file and deleting that event" * tag 'trace-3.11-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Kill the unbalanced tr->ref++ in tracing_buffers_open() tracing: Kill trace_array->waiter tracing: Do not (ab)use trace_seq in event_id_read() tracing: Simplify the iteration logic in f_start/f_next tracing: Add ref_data to function and fgraph tracer structs tracing: Miscellaneous fixes for trace_array ref counting tracing: Fix error handling to ensure instances can always be removed tracing/kprobe: Wait for disabling all running kprobe handlers tracing/perf: Move the PERF_MAX_TRACE_SIZE check into perf_trace_buf_prepare() tracing/syscall: Avoid perf_trace_buf_*() if sys_data->perf_events is empty tracing/function: Avoid perf_trace_buf_*() if event_function.perf_events is empty tracing: Typo fix on ring buffer comments tracing: Use trace_seq_puts()/trace_seq_putc() where possible tracing: Use correct config guard CONFIG_STACK_TRACER
