2 *  IMFS_mount
3 * 
4 *  This routine will look at a mount table entry that we are going to
5 *  add to the mount table. If the mount point rtems_filesystem
6 *  location_info_t struct refers to a node that is a directory,
7 *  the node will be marked as a mount point by setting its directory.mt_fs
8 *  pointer to point to the mount table entry that we are about to add
9 *  to the mount table chain.
