mainlining shenanigans

Currently the struct space_info creation code is intermixed in the udpate_space_info function. There are well-defined points at which the we actually want to create brand-new space_info structs (e.g. during mount of the filesystem as well as sometimes when adding/initialising new chunks). In such cases update_space_info is called with 0 as the bytes parameter. All of this makes for spaghetti code. Fix it by factoring out the creation code in a separate create_space_info structure. This also allows to simplify the internals. Also remove BUG_ON from do_alloc_chunk since the callers handle errors. Furthermore it will make the update_space_info function not fail, allowing us to remove error handling in callers. This will come in a follow up patch.

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.
