Merge tag 'trace-4.1-tracefs' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracefs from Steven Rostedt: "This adds the new tracefs file system. This has been in linux-next for more than one release, as I had it ready for the 4.0 merge window, but a last minute thing that needed to go into Linux first had to be done. That was that perf hard coded the file system number when reading /sys/kernel/debugfs/tracing directory making sure that the path had the debugfs mount # before it would parse the tracing file. This broke other use cases of perf, and the check is removed. Now when mounting /sys/kernel/debug, tracefs is automatically mounted in /sys/kernel/debug/tracing such that old tools will still see that path as expected. But now system admins can mount tracefs directly and not need to mount debugfs, which can expose security issues. A new directory is created when tracefs is configured such that system admins can now mount it separately (/sys/kernel/tracing)" * tag 'trace-4.1-tracefs' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Have mkdir and rmdir be part of tracefs tracefs: Add directory /sys/kernel/tracing tracing: Automatically mount tracefs on debugfs/tracing tracing: Convert the tracing facility over to use tracefs tracefs: Add new tracefs file system tracing: Create cmdline tracer options on tracing fs init tracing: Only create tracer options files if directory exists debugfs: Provide a file creation function that also takes an initial size
