In some cases readahead of more than the read size can help (to allow parallel i/o of read ahead which can improve performance). Ceph introduced a mount parameter "rasize" to allow controlling this. Add mount parameter "rasize" to allow control of amount of readahead requested of the server. If rasize not set, rasize defaults to negotiated rsize as before.

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.
