I think then we should probably make the driver simpler and remove the special case for the two resources... any small saving of using just two resources is probably cancelled out by the extra code needed. > +#define res_size(_r) (((_r)->end - (_r)->start) + 1) > + I'd like to see something like this as an inline function in the relevant header, and some patches to get other users to find it. > - > if (pdata->outblk != NULL) > db->outblk = pdata->outblk; > - > if (pdata->dumpblk != NULL) > db->dumpblk = pdata->dumpblk; I'd rather not see spacing changes done, especially as I don't like to see lots of code cramped together. -- Ben (ben@xxxxxxxxx, http://www.fluff.org/) 'a smiley only costs 4 bytes' -- To unsubscribe from this list: send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
