Head SHA1: 092adb1121aec9e0dfa2d07bc160ae60831f4798


Steven Rostedt (VMware) (8):
      tracing: Add ftrace_hash_key() helper function
      ftrace: Create a slight optimization on searching the ftrace_hash
      ftrace: Replace (void *)1 with a meaningful macro name FTRACE_GRAPH_EMPTY
      ftrace: Reset fgd->hash in ftrace_graph_write()
      ftrace: Have set_graph_functions handle write with RDWR
      tracing: Reset parser->buffer to allow multiple "puts"
      ftrace: Do not hold references of ftrace_graph_{notrace_}hash out of graph_lock
      ftrace: Have set_graph_function handle multiple functions in one write
