 * Inputs:
 *   pathname - the full path to a registered block driver
 *
 * Return:
 *   Zero (OK) on success;
 *   -1 (ERROR) on failure with errno set appropriately:
 *
 *   EINVAL - NULL block driver string
 *   ENOENT - 'pathname' does not refer to anything in the filesystem.
 *   ENOTBLK - 'pathname' does not refer to a block driver
 *   EFTYPE - the block driver hasn't been formatted yet

 * Name: mksmartfs

 * Description:
 *   Make a SMART (Sector Mapped Allocation for Really Tiny) Flash file
 *   system image on the specified block device (must be a SMART device).
 *
 * Inputs:
 *   pathname - the full path to a registered block driver
 *   nrootdirs - the number of Root Directory entries to support
 *               on this device (supports multiple mount points).
 *
 * Return:
 *   Zero (OK) on success;
 *   -1 (ERROR) on failure with errno set appropriately:
 *
 *   EINVAL - NULL block driver string
 *   ENOENT - 'pathname' does not refer to anything in the filesystem.
 *   ENOTBLK - 'pathname' does not refer to a block driver
 *   EACCESS - block driver does not support write or geometry methods or
 *             is not a SMART device
 *
 * Assumptions:
 *   - The caller must assure that the block driver is not mounted and not in
 *     use when this function is called.  The result of formatting a mounted
 *     device is indeterminate (but likely not good).
