Merge branch 'debugfs_automount' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs into trace/ftrace/tracefs
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.
