From ZBC-1: - RC BASIS = 0: The RETURNED LOGICAL BLOCK ADDRESS field indicates the highest LBA of a contiguous range of zones that are not sequential write required zones starting with the first zone. - RC BASIS = 1: The RETURNED LOGICAL BLOCK ADDRESS field indicates the LBA of the last logical block on the logical unit. The current scsi_debug READ CAPACITY response does not comply with the above if there are one or more sequential write required zones. SCSI initiators need a way to retrieve the largest valid LBA from SCSI devices. Reporting the largest valid LBA if there are one or more sequential zones requires to set the RC BASIS field in the READ CAPACITY response to one. Hence this patch.

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.
