Keepo in mind that rw_copy_check_uvector() does, among other things, verify that total length is less than 2^31.

For this conversion I just kept the type that used to be there. -- 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
