When a user tries to parse a symbol located inside a module he must have modpath set. Otherwise, decode_stacktrace won't be able to parse the symbol correctly. Right now the failure is silent and easily missed by the user. What's worse is that by the time the user realizes what happened (or someone on LKML asks him to add the modpath and re-run), he might have already got rid of the vmlinux/modules.

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.
