Initialization of blk-mq requests is a bit weird: blk_mq_rq_ctx_init() is called after a value has been assigned to .rq_flags and .rq_flags is initialized in __blk_mq_finish_request(). Initialize .rq_flags in blk_mq_rq_ctx_init() instead of relying on __blk_mq_finish_request(). Moving the initialization of .rq_flags is fine because all changes and tests of .rq_flags occur between blk_get_request() and finishing a request.

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.
