commit 9e1cdf0c354e46e428c0e0cab008abbe81b6013d upstream.
btrfs_can_activate_zone() returns true if at least one device has one zone
available for activation. This is OK for the single profile, but not OK for
DUP profile. We need two zones to create a DUP block group. Fix it by
properly handling the case with the profile flags.
Fixes: 265f7237dd25 ("btrfs: zoned: allow DUP on meta-data block groups")

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.
