fs/nfsd/nfs4callback.c implements a callback client. Thus its XDR
decoders are decoding replies, not calls.
NFS4ERR_BAD_XDR is an on-the-wire status code that reports that the
client sent a corrupted RPC /call/. It's not used as the internal
error code when a /reply/ can't be decoded, since that kind of
failure is never reported to the sender of that RPC message.
Instead, a reply decoder should return -EIO, as the reply decoders
in the NFS client do.

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 reStructuredText 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.
