Revision d2b7fa6174bc4260e496cbf84375c73636914641 authored by Breno Leitao on 04 May 2023, 12:18:56 UTC, committed by Jens Axboe on 04 May 2023, 14:19:05 UTC
In the io_uring_cmd_prep_async() there is an unnecessary compilation time check to check if cmd is correctly placed at field 48 of the SQE. This is unnecessary, since this check is already in place at io_uring_init(): BUILD_BUG_SQE_ELEM(48, __u64, addr3); Remove it and the uring_cmd_pdu_size() function, which is not used anymore. Keith started a discussion about this topic in the following thread: Link: https://lore.kernel.org/lkml/ZDBmQOhbyU0iLhMw@kbusch-mbp.dhcp.thefacebook.com/ Signed-off-by: Breno Leitao <leitao@debian.org> Reviewed-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Pavel Begunkov <asml.silence@gmail.com> Link: https://lore.kernel.org/r/20230504121856.904491-4-leitao@debian.org Signed-off-by: Jens Axboe <axboe@kernel.dk>

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
