Initial global namespace mount support; there is still an unmount bug,
where it gets the wrong superblock, so I don't advise trying this code

NB: It requires a kernel patch, and vanilla-2.4.20 is the only kernel
updated thus far.

void ll_close_thread_shutdown(struct ll_close_queue *lcq);
int ll_close_thread_start(struct ll_close_queue **lcq_ret);
+int ll_dir_process_mount_object(struct dentry *, struct nameidata *);
