In the following patch, we will use RQF_FLUSH_SEQ to decide: 1) if the flag isn't set, the flush rq need to be inserted via blk_insert_flush() 2) otherwise, the flush rq need to be dispatched directly since it is in flush machinery now. So we use blk_mq_request_bypass_insert() for requests of bypassing flush machinery, just like the legacy path did.

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.
