Use the address alignment requirements from the block_device for direct io instead of requiring addresses be aligned to the block size. User space can discover the alignment requirements from the dma_alignment queue attribute. User space can specify any hardware compatible DMA offset for each segment, but every segment length is still required to be a multiple of the block size.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
