In this case, shouldn't we just have a loop where: 1. from the given endpoint, we go a semiblock back 2. now we see how many bytes we get when fetching the SG list till the end, 3a. if answer from 2 is semiblock or larger -> fetch it and exit 3b. if answer from 2 is less than a semiblock, fetch the available data, advance to the next SGL and go to step 2 to try to fetch semiblock - obtained data. -- Ciao Stephan -- To unsubscribe from this list: send the line "unsubscribe linux-crypto" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
