Previously, we attempt to flush the whole cp pack in a single bio, however, when suddenly powering off at this time, we could get into an extreme scenario that cp pack 1 page and cp pack 2 page are updated and latest, but payload or current summaries are still partially outdated. (see reliable write in the UFS specification) This patch submits the whole cp pack except cp pack 2 page at first, and then writes the cp pack 2 page with an extra independent bio with pre-io barrier.

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.
