Subject: [PATCH 09/12] io_uring: don't delay io_init_req() error check
Date: Sat, 10 Oct 2020 18:34:13 +0100 [thread overview]
Message-ID: <98920d5293ac3ecb048442ae4cfe6f4dd732b3db.1602350806.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>
Don't postpone io_init_req() error checks and do that right after
calling it. There is no control-flow statements or dependencies with
sqe/submitted accounting, so do those earlier, that makes the code flow
a bit more natural.
