We have had several bugs due mixing sector and logical block size terminology. In the block layer, a sector is a 512-byte unit regardless of the logical block size of the underlying device. But the term "sector" is still widely used in sd.c when referring to logical block sized units. We previously introduced helper functions such as sectors_to_logical() and logical_to_sectors() to make the distinction clear. Use these to make the code in sd.c consistent wrt. logical blocks and block layer sectors. Use "lba" to describe a logical block address and "nr_blocks" when counting logical blocks. SBC uses "TRANSFER LENGTH" to describe the latter but this term was avoided to prevent confusion with the very similar DMA transfer size (->transfersize) which is counted in bytes.

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.
