Herbert Xu	e70308ec0e	Revert "crypto: crct10dif - Wrap crc_t10dif function all to use crypto transform framework" ... This reverts commits 67822649d7 39761214ee 0b95a7f857 31d939625a 2d31e518a4 Unfortunately this change broke boot on some systems that used an initrd which does not include the newly created crct10dif modules. As these modules are required by sd_mod under certain configurations this is a serious problem. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>	2013-07-24 17:04:16 +10:00
Herbert Xu	67822649d7	crypto: crct10dif - Use PTR_RET ... lib/crc-t10dif.c:42:1-3: WARNING: PTR_RET can be used Use PTR_RET rather than if(IS_ERR(...)) + PTR_ERR Generated by: coccinelle/api/ptr_ret.cocci Reported-by: Fengguang Wu <fengguang.wu@intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>	2013-06-05 16:27:51 +08:00
Tim Chen	2d31e518a4	crypto: crct10dif - Wrap crc_t10dif function all to use crypto transform framework ... When CRC T10 DIF is calculated using the crypto transform framework, we wrap the crc_t10dif function call to utilize it. This allows us to take advantage of any accelerated CRC T10 DIF transform that is plugged into the crypto framework.

Martin K. Petersen	f11f594edb	[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.
