Fragments and dedupe share one feature bit, and thus packed inode may not exist when fragment feature bit (dedupe feature bit exactly) is set, e.g. when deduplication feature is in use while fragments feature is not. In this case, sbi->packed_inode could be NULL while fragments feature bit is set. Fix this by accessing packed inode only when it exists.

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.
