	help
	  This option is provided for the case where no in-kernel-tree
	  modules require CRC-CCITT functions, but a module built outside
	  the kernel tree does. Such modules that use library CRC-CCITT
	  functions require M here.

	  functions require M here.

config CRC_T10DIF

	  This option is only needed if a module that's not in the
	  kernel tree needs to calculate CRC checks for use with the
	  SCSI data integrity subsystem.

config CRC_ITU_T

	  This option is provided for the case where no in-kernel-tree
