Tomo, List Please find a second version of the patch to add support to have backends reject opcodes they dont implement with INVALID_OP_CODE. This patch adds this capability to RDWR and SHEEPDOG. I changed the implamentation from the first patch based on comments from Dan Mick and are now using a much more human friendly way to specify which opcodes are supproted. This is now done by simply creating an array with all the defines for the opcode names. The ones that are listed in static char opcodes[] are the opcodes that the backend supports, the ones not listed will be returned as INVALID_OP_CODE regards ronnie sahlberg -- To unsubscribe from this list: send the line "unsubscribe stgt" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
