Subject: [PATCH 7/8] io_uring/net: refactor io_sr_msg types
Date: Thu, 8 Sep 2022 13:20:33 +0100 [thread overview]
Message-ID: <42c2639d6385b8b2181342d2af3a42d3b1c5bcd2.1662639236.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>
In preparation for using struct io_sr_msg for zerocopy sends, clean up
types. First, flags can be u16 as it's provided by the userspace in u16
ioprio, as well as addr_len. This saves us 4 bytes. Also use unsigned
for size and done_io, both are as well limited to u32.
