[for-next][PATCH 0/8] tracing: Some micro optimizations

Show all headers | View raw

Andi Kleen pointed out a trace that showed lots of functions being
called in the trace event hot path. These functions would help to
be inlined. More needs to be done, but this is just a start.

Steven Rostedt (Red Hat) (8):
      tracing: Create a always_inlined __trace_buffer_lock_reserve()
      ring-buffer: Make rb_reserve_next_event() always inlined
      ring-buffer: Always inline rb_event_data()
      tracing: Make tracepoint_printk a static_key
      tracing: Make __buffer_unlock_commit() always_inline
      ring-buffer: Force inline of hotpath helper functions
      ring-buffer: Froce rb_update_write_stamp() to be inlined
      ring-buffer: Force rb_end_commit() and rb_set_commit_to_write() inline
