This patch series implements a cached report zones using information from the block layer zone write plugs and a new zone condition tracking. This avoids having to execute slow report zones commands on the device when for instance mounting file systems, which can significantly speed things up, especially in setups with multiple SMR HDDs (e.g. a BTRFS RAID volume). The first patch improves handling of zone management commands. Patch 2 fixes zone resource updates and the following 3 patches cleanup the zone code in preparation for introducing cached zone report support. From patch 6 to 13, cached report zones is implemented and made available to users with a new ioctl() command. Finally, patches 14 and 15 introduce the use of cached report zones in the mount operation of XFS and BTRFS.

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.
