In the spirit of fairness, cap the max number of SQ entries we'll submit for SQPOLL if we have multiple rings. If we don't do that, we could be submitting tons of entries for one ring, while others are waiting to get service. The value of 8 is somewhat arbitrarily chosen as something that allows a fair bit of batching, without using an excessive time per ring. 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.
