Currently should_alloc_chunk uses ->total_bytes - ->bytes_readonly to signify the total amount of bytes in this space info. However, given Jeff's patch which adds bytes_pinned and bytes_may_use to the calculation of num_allocated it becomes a lot more clear to just eliminate num_bytes altogether and add the bytes_readonly to the amount of used space. That way we don't change the results of the following statements. In the process also start using btrfs_space_info_used.

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.
