Subject: [PATCH 6/8] io_uring: clean io_prep_rw()
Date: Fri, 15 Oct 2021 17:09:16 +0100 [thread overview]
Message-ID: <2f5889fc7ab670daefd5ccaedd99416d8355f0ad.1634314022.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>
We already store req->file in a variable in io_prep_rw(), just use it
instead of a couple of left references to kicob->ki_filp.
