From: Luke Hsiao <lukehs...@google.com> This patch series adds support for reading MSG_ERRQUEUE using the io_uring interface. Support for this operation allows io_uring to serve as an alternative to epoll + recvmsg for reading notification completions for TCP tx zerocopy.
The first patch allows ancillary data to be read using recvmsg from io_uring, while the second patch provides an optimization for reading these notification completions.
