Re: [CFT][PATCH 08/10] sysfs: Add support for permanently empty directories to serve as mount points.

Add two functions sysfs_create_mount_point and sysfs_remove_mount_point
that hang a permanently empty directory off of a kobject or remove a
permanently emptpy directory hanging from a kobject.  Export these new
functions so modular filesystems can use them.
