This patch changes the behavior of the lightnvm driver as follows: * REQ_FAILFAST_MASK is set for read-ahead requests. * If no I/O priority has been set in the bio, the I/O priority is copied from the I/O context. * The rq_disk member is initialized if bio->bi_bdev != NULL. * The bio sector offset is copied into req->__sector instead of retaining the value -1 set by blk_mq_alloc_request(). * req->errors is initialized to zero.

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.
