Petersen" Date: Wed, 25 Jun 2008 11:22:42 -0400 Subject: [SCSI] lib: Add support for the T10 (SCSI) Data Integrity Field CRC The SCSI Block Protocol uses this 16-bit CRC to verify the integrity of each data sector. crc_t10dif() is used by sd_dif.c when performing I/O to or from disks formatted with protection information.
