903 * The '-s' flag applies only to volumes, and indicates that we should not try
904 * to set the reservation for this volume. By default we set a reservation
905 * equal to the size for any volume. For pools with SPA_VERSION >=
906 * SPA_VERSION_REFRESERVATION, we set a refreservation instead.
907 *
908 * The '-p' flag creates all the non-existing ancestors of the target first.

910 * The '-n' flag is no-op (dry run) mode. This will perform a user-space sanity
911 * check of arguments and properties, but does not check for permissions,
912 * available space, etc.
913 *
914 * The '-v' flag is for verbose output.
915 *
916 * The '-P' flag is used for parseable output. It implies '-v'.
