Merge branch 'debugfs_automount' of git://git.kernel.org/pub/scm/linux/kernel/git...

Pull in Al Viro's changes to debugfs that implement the new primitive:
debugfs_create_automount(), that creates a directory in debugfs that will
safely mount another file system automatically when debugfs is mounted.

This will let tracefs automount itself on top of debugfs/tracing directory.
