Now that we factored xfs_buf_find(), we can start separating into distinct fast and slow paths from xfs_buf_get_map(). We start by moving the lookup map and perag setup to _get_map(), and then move all the specifics of the fast path lookup into xfs_buf_lookup() and call it directly from _get_map(). We the move all the slow path code to xfs_buf_find_insert(), which is now also called directly from _get_map(). As such, xfs_buf_find() now goes away.

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.
