xfs_attr_sf_findname has the simple job of finding a xfs_attr_sf_entry in the attr fork, but the convoluted calling convention obfuscates that. Return the found entry as the return value instead of an pointer argument, as the -ENOATTR/-EEXIST can be trivally derived from that, and remove the basep argument, as it is equivalent of the offset of sfe in the data for if an sfe was found, or an offset of totsize if not was found. To simplify the totsize computation add a xfs_attr_sf_endptr helper that returns the imaginative xfs_attr_sf_entry at the end of the current attrs.

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.
