Currently any dependent link is executed from a new workqueue context, which means that we'll be doing a context switch per link in the chain. If we are running the completion of the current request from our async workqueue and find that the next request is a link, then run it directly from the workqueue context instead of forcing another switch. This improves the performance of linked SQEs, and reduces the CPU overhead. Reviewed-by: Jackie Liu <liuyun01@kylinos.cn> 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.
