Currently videobuf2-dma-sg checks for dma direction for every single page and videobuf2-dc lacks any dma direction checks and calls set_page_dirty_lock unconditionally. Thus unify and align the invocations of set_page_dirty_lock for videobuf2-dc, videobuf2-sg memory allocators with videobuf2-vmalloc, i.e. the pattern used in vmalloc has been copied to dc and dma-sg.

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.
