+ *  IMFS_mount

+ *  This routine will look at a mount table entry that we are going to
+ *  add to the mount table. If the mount point rtems_filesystem
+ *  location_info_t struct refers to a node that is a directory,
+ *  the node will be marked as a mount point by setting its directory.mt_fs
+ *  pointer to point to the mount table entry that we are about to add
+ *  to the mount table chain.
