VFS: Add GPL_EXPORTED function vfs_kern_mount()
do_kern_mount() does not allow the kernel to use private mount interfaces without exposing the same interfaces to userland. The problem is that the filesystem is referenced by name, thus meaning that it and its mount interface must be registered in the global filesystem list. vfs_kern_mount() passes the struct file_system_type as an explicit parameter in order to overcome this limitation.
