All good users should not set IOSQE_IO_*LINK flags for the last request of a link. io_uring flushes collected links at the end of submission, but it's not the optimal way and so we don't care too much about it. Replace io_queue_sqe() call with io_queue_sqe_fallback() as the former one is inlined and will generate a bunch of extra code. This will also help compilers with the submission path inlining. > size ./fs/io_uring.o text data bss dec hex filename 87265 13734 8 101007 18a8f ./fs/io_uring.o > size ./fs/io_uring.o text data bss dec hex filename 87073 13734 8 100815 189cf ./fs/io_uring.o Signed-off-by: Pavel Begunkov <asml.silence@gmail.com> Link: https://lore.kernel.org/r/01fb5e417ef49925d544a0b0bae30409845ed2b4.1649771823.git.asml.silence@gmail.com Signed-off-by: Jens Axboe <axboe@kernel.dk> |

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.
