From: "Steven Rostedt (VMware)" <rostedt@xxxxxxxxxxx> The first three patches are helper functions to help with the final patch, although the second patch can probably stand on its own, as it simplifies access to the files in the system/event/ directory, instead of having to build it first and then call tracefs_instance_file_*().
