[ Upstream commitb5a711acab] The current logic, regardless of whether CONFIG_BLK_DEV_ZONED is enabled or not, will judge whether discard_unit is SECTION, when f2fs_sb_has_blkzoned. In fact, when CONFIG_BLK_DEV_ZONED is not enabled, this judgment is a path that will never be accessed. At this time, -EINVAL will be returned in the parse_options function, accompanied by the message "Zoned block device support is not enabled". Let's wrap this discard_unit judgment with CONFIG_BLK_DEV_ZONED.

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.
