This patch enables write IO to transfer data to backing device. For that, it implements write_to_bdev function which creates new bio and chaining with parent bio to make the parent bio asynchrnous. For rw_page which don't have parent bio, it submit owned bio and handle IO completion by zram_page_end_io. Also, this patch defines new flag ZRAM_WB to mark written page for later read IO.

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.
