commit4f993264fe("f2fs: introduce discard_unit mount option") introduced a bug, when we enable discard_unit=section option, it will set .discard_granularity to BLKS_PER_SEC(), however discard granularity only supports [1, 512], once section size is not equal to segment size, it will cause issue_discard_thread() in DPOLICY_BG mode will not select discard entry w/ any granularity to issue.

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.
