AF: From: Boaz Harrosh <bharrosh@xxxxxxxxxxx> Subject: [RFC 4/8] scsi-ml: scsi_sgtable implementation Date: Thu, 05 Jul 2007 16:43:42 +0300 > As proposed by James Bottomley all I/O members of struc scsi_cmnd > and the resid member, which need to be duplicated for bidirectional > transfers. Can be allocated together with the sg-list they are > pointing to. This way when bidi comes the all structure can be duplicated > with minimal change to code, and with no extra baggage when bidi is not > used. The resulting code is the use of a new mechanism called scsi_sgtable. > (Old code will be removed in next patch for easier reviewing) I think that it would be better to push this with Jens' sglist and bidi support together to mainline. Changing the scsi-ml sg code and testing it again and again doesn't sound nice. - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
