This driver stores the currently addressed page into denali->page, which is later read out by helper functions. While I am tackling on this driver, I often missed to insert "denali->page = page;" where needed. This makes page_read/write callbacks to get access to a wrong page, which is a bug hard to figure out. Instead, I'd rather pass the page via function argument because the compiler's prototype checks will help to detect bugs. For the same reason, propagate dma_addr to the DMA helpers instead of denali->buf.dma_buf .

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.
