I recently had to look at a production problem where a request ended up getting the dreaded -EINVAL error on submit. The most used and hence useless of error codes, as it just tells you that something was wrong with your request, but not more than that. Let's dump the full sqe contents if we run into an issue failure, that'll allow easier diagnosing of a wide variety of issues. 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.
