xfs_has_attr() is poorly named. It has global scope as it is defined in a header file, but it has no namespace scope that tells us what it is checking has attributes. It's not even clear what "has_attr" means, because what it is actually doing is an attribute fork lookup to see if the attribute exists. Upcoming patches use this "xfs_has_<foo>" namespace for global filesystem features, which conflicts with this function. Rename xfs_has_attr() to xfs_attr_lookup() and make it a static function, freeing up the "xfs_has_" namespace for global scope usage.

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.
