Hi, I have few doubts related to iovec & kvec structures, in particular related to using these strucutes for sending the data over the socket using kernel_sendmsg()/sock_sendmsg(). Doubts - 1) Can we pass iovec to kernel_sendmsg() instead of kvecs? Is it recommended to use kvec instead of iovec ? 2) What are differences between kvec vs iovec ? >From the definition of these structures, I see that iovec has _user type, so it may point to a user buffer. Are there some other differences between kvec or iovec ? 3) When shall we use kvec instead of iovec ? 4) For iterating the iovecs, I could find one macro -- 'iov_for_each' which uses iov_iterator. Is there similar easy way to iterate the kvec ?
