perf tools: Move tracing_path stuff under same namespace
Renaming all functions touching tracing_path under same namespace. New interface is: char tracing_path[]; - tracing mount path char tracing_events_path[]; - tracing mount/events path void tracing_path_set(const char *mountpoint); - setting directly tracing_path(_events), used by --debugfs-dir option const char *tracing_path_mount(void); - initial setup of tracing_(events)_path, called from perf.c mounts debugfs/tracefs if needed and possible char *get_tracing_file(const char *name); void put_tracing_file(char *file); - get/put tracing file path Signed-off-by: Jiri Olsa <jolsa@kernel.org> Cc: Raphael Beamonte <raphael.beamonte@gmail.com> Cc: David Ahern <dsahern@gmail.com> Cc: Matt Fleming <matt@codeblueprint.co.uk> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Steven Rostedt <rostedt@goodmis.org> Link: http://lkml.kernel.org/r/1441180605-24737-4-git-send-email-jolsa@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
