Zone append operations are only allowed to target sequential write required zones. blk_check_zone_append() uses bio_zone_is_seq() to check this. However, this check is not necessary because: 1) For NVMe ZNS namespace devices, only sequential write required zones exist, making the zone type check useless. 2) For null_blk, the driver will fail the request anyway, thus notifying the user that a conventional zone was targeted. 3) For all other zoned devices, zone append is now emulated using zone write plugging, which checks that a zone append operation does not target a conventional zone. In preparation for the removal of zone write locking and its conventional zone bitmap (used by bio_zone_is_seq()), remove the bio_zone_is_seq() call from blk_check_zone_append().

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 reStructuredText 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.
