Stefan Metzmacher e307e66981 io_uring/net: introduce IORING_SEND_ZC_REPORT_USAGE flag ... It might be useful for applications to detect if a zero copy transfer with SEND[MSG]_ZC was actually possible or not. The application can fallback to plain SEND[MSG] in order to avoid the overhead of two cqes per request. Or it can generate a log message that could indicate to an administrator that no zero copy was possible and could explain degraded performance.
