This series fixes a few small problems in Orit's writev patches: 1) socket_put_buffer is not needed anymore and can be dropped (patch 1);
2) sendmsg could do a partial write even for a blocking socket, in case it is interrupted by a signal. This should not happen for migration, but it is relatively easy to fix in iov_send_recv (patches 2 to 5); 3) recent libvirt will always use fd migration, and thus will not benefit from the writev speedups. fd migration also uses FILE*, which incurs an extra copy. Patch 6 fixes both issues. Thanks, Paolo Paolo Bonzini (6): qemu-file: drop socket_put_buffer iov: reorganize iov_send_recv, part 1 iov: reorganize iov_send_recv, part 2 iov: reorganize iov_send_recv, part 3 iov: handle partial writes from sendmsg and recvmsg qemu-file: do not use stdio for qemu_fdopen savevm.c | 113 ++++++++++++++++++++++++++++++++++++++++++++++++------------- util/iov.c | 104 ++++++++++++++++++++++++++++++++------------------------ 2 files changed, 148 insertions(+), 69 deletions(-) -- 1.8.1.4
