The notable changes are: - instead of explicitly stat'ing the object to see if it exists before issuing the write, send the write optimistically along with the stat in a single OSD request - zero copyup optimization - all object requests are associated with an image request and have a valid ->img_request pointer; there are no standalone (!IMG_DATA) object requests anymore - code is structured as a state machine (vs a bunch of callbacks with implicit state) Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
