Replace bdev_direct_access() with dax_direct_access() that uses dax_device and dax_operations instead of a block_device and block_device_operations for dax. Once all consumers of the old api have been converted bdev_direct_access() will be deleted. Given that block device partitioning decisions can cause dax page alignment constraints to be violated this also introduces the bdev_dax_pgoff() helper. It handles calculating a logical pgoff relative to the dax_device and also checks for page alignment. Signed-off-by: Dan Williams <dan.j.williams@intel.com>
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.
