commit 77900c45ee5cd5da63bd4d818a41dbdf367e81cd upstream. In fuzzed image, SSA table may indicate that a data block belongs to invalid node, which node ID is out-of-range (0, 1, 2 or max_nid), in order to avoid migrating inconsistent data in such corrupted image, let's do sanity check anyway before data block migration.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
