Dave Chinner 51b495eba8 xfs: rename xfs_has_attr()
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.
