From: Pavel Begunkov <asml.silence@xxxxxxxxx> [ upstream commit 0b048557db761d287777360a100e1d010760d209 ] 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.
