pg_temp and pg_upmap encodings are the same (PG -> array of osds), except for the incremental remove: it's an empty mapping in new_pg_temp for pg_temp and a separate old_pg_upmap set for pg_upmap. (This isn't to allow for empty pg_upmap mappings -- apparently, pg_temp just wasn't looked at as an example for pg_upmap encoding.) Reuse __decode_pg_temp() for decoding pg_upmap and new_pg_upmap. __decode_pg_temp() stores into pg_temp union member, but since pg_upmap union member is identical, reading through pg_upmap later is OK.

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.
