It is possible that an osc_extent contains more than 256 chunks, and the IO engine won't add this extent in one RPC (try_to_add_extent_for_io) so that osc_check_rpcs() run into a loop upon this extent and never break. This patch changes osc_max_write_chunks() to make sure the value can cover all possible osc_extent, so that all osc_extent will be added into one RPC. This patch also add another field erd_max_extents in extent_rpc_data to make sure not to add too many fragments in a single RPC.

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.
