That was the only thing I could think of too. I haven't made any attempt to figure out how much of the code size comes from the various inlined user-memory copying functions that call access_ok, and could be reworked not to inline any of the uncommon paths, vs direct uses of access_ok in miscellaneous code. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
