When iterating the backrefs in an extent item if the ptr to the 'current' backref record goes beyond the extent item a warning is generated and -ENOENT is returned. However what's more appropriate to debug such cases would be to return EUCLEAN and also print identifying information about the performed search as well as the current content of the leaf containing the possibly corrupted extent item.

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.
