Subject: [PATCH 1/9] io_uring: net: don't check sqe->__pad2[0] for send zc
Date: Mon, 8 Apr 2024 09:03:14 +0800 [thread overview]
Message-ID: <[email protected]> (raw)
In-Reply-To: <[email protected]>
send_zc never uses any byte in sqe->__pad2[], and the check is
unnecessary, so remove it and prepare for using the last byte
as sqe extended flags.
