Christoph noticed that the xfs_attr_is_leaf in xfs_attr_get_ilocked can access the incore extent tree of the attr fork, but nothing in the xfs_attr_get path guarantees that the incore tree is actually loaded. Most of the time it is, but seeing as xfs_attr_is_leaf ignores the return value of xfs_iext_get_extent I guess we've been making choices based on random stack contents and nobody's complained?

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.
