Or Gerlitz 8e8a5f7c28 nvme/tcp: Use writev_async for sending data on sockets ... Amortize the writev syscall cost by using the writev_async socket API. This allows the socket layer to batch writes into one system call and also apply further optimizations such as posix's MSG_ZEROCOPY when they are available. As part of doing so we remove the error return in the socket layer writev_async implementation for sockets that don't have a poll group. Doing so eliminates the send queue processing.
