Most of them are mere consumers of > sgs... Some scsi drivers like ips access to sglist in a tricky way. I feel that they don't work with the sg_ring interface well. So if you convert scsi_lib.c to use sg_ring, please see how it works with the tricky drivers before that. > I'm not a SCSI person: I'm patching SCSI because I have to to get my > own sg-using code clean :) I'm SCSI-biased. If you don't convert scsi to use sg_ring, I don't complain. :) Though it would be better to have only one mechanism to handle large sglist in kernel. - 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
