[ Upstream commitb5f1a218ae] In the DPOLICY_BG mode, there is a conflict between the two conditions "i + 1 < dpolicy->granularity" and "i < DEFAULT_DISCARD_GRANULARITY". If i = 15, the first condition is false, it will enter the second condition and dispatch all small granularity discards in function __issue_discard_cmd_orderly. The restrictive effect of the first condition to small discards will be invalidated. These two conditions should align.

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.
