Colin Ian King (1):
ftrace: Remove unused pointer ftrace_swapper_pid
Erica Bugden (1):
ftrace: Add missing check for existing hwlat thread
Francis Deslauriers (1):
selftest/ftrace: Move kprobe selftest function to separate compile unit
Gustavo A. R. Silva (1):
ftrace: Use true and false for boolean values in ops_references_rec()
Joel Fernandes (Google) (9):
srcu: Add notrace variant of srcu_dereference
tracing/irqsoff: Split reset into separate functions
lib: Add module for testing preemptoff/irqsoff latency tracers
kselftests: Add tests for the preemptoff and irqsoff tracers
lockdep: Use this_cpu_ptr instead of get_cpu_var stats
tracepoint: Make rcuidle tracepoint callers use SRCU
tracing: Centralize preemptirq tracepoints and unify their usage
trace: Use rcu_dereference_raw for hooks from trace-event subsystem
tracing: irqsoff: Account for additional preempt_disable
Masami Hiramatsu (5):
tracing: Remove orphaned function using_ftrace_ops_list_func().
tracing: Remove orphaned function ftrace_nr_registered_ops()
tracing: kprobes: Prohibit probing on notrace function
selftests/ftrace: Fix kprobe string testcase to not probe notrace function
tracing/kprobes: Fix within_notrace_func() to check only notrace functions
Paul McKenney (1):
srcu: Add notrace variants of srcu_read_{lock,unlock}
Steven Rostedt (VMware) (13):
tracing: Make unregister_trigger() static
tracing/kprobes: Simplify the logic of enable_trace_kprobe()
tracing: Do not call start/stop() functions when tracing_on does not
change
tracing: Do a WARN_ON() if start_thread() in hwlat is called when thread
exists
tracing: Make tracer_tracing_is_on() return bool
ring-buffer: Make ring_buffer_record_is_on() return bool
ring-buffer: Make ring_buffer_record_is_set_on() return bool
tracing: Partial revert of "tracing: Centralize preemptirq tracepoints
and unify their usage"
tracing/irqsoff: Handle preempt_count for different configs
tracing: More reverting of "tracing: Centralize preemptirq tracepoints
and unify their usage"
tracing: Fix synchronizing to event changes with
tracepoint_synchronize_unregister()
uprobes: Use synchronize_rcu() not synchronize_sched()
tracepoints: Free early tracepoints after RCU is initialized
Zubin Mithra (1):
tracefs: Annotate tracefs_ops with __ro_after_init
kbuild test robot (1):
tracing: preemptirq_delay_run() can be static
