This moves the prep handlers outside of the opcode handlers, and allows us to pass in the sqe directly. If the sqe is non-NULL, it means that the request should be prepared for the first time. With the opcode handlers not having access to the sqe at all, we are guaranteed that the prep handler has setup the request fully by the time we get there. As before, for opcodes that need to copy in more data then the io_kiocb allows for, the io_async_ctx holds that info. If a prep handler is invoked with req->io set, it must use that to retain information for later. Finally, we can remove io_kiocb->sqe as well. 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.
