Modify xfs_mount_zones() to replace the call to blkdev_report_zones() with blkdev_report_zones_cached() to speed-up mount operations. Since this causes xfs_zone_validate_seq() to see zones with the BLK_ZONE_COND_ACTIVE condition, this function is also modified to acept this condition as valid. With this change, mounting a freshly formatted large capacity (30 TB) SMR HDD completes under 2s compared to over 4.7s before.

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.
