ZBC or ZAC disks that have a limit on the number of open zones may fail a zone open command or a write to a zone that is not already implicitly or explicitly open if the total number of open zones is already at the maximum allowed. For these operations, instead of returning the generic BLK_STS_IOERR, return BLK_STS_ZONE_OPEN_RESOURCE which is returned as -ETOOMANYREFS to the I/O issuer, allowing the device user to act appropriately on these relatively benign zone resource errors.

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.
