Gabriel Niebler 4076942021 btrfs: turn name_cache radix tree into XArray in send_ctx
… and adjust all usages of this object to use the XArray API for the sake
of consistency.

XArray API provides array semantics, so it is notionally easier to use and
understand, and it also takes care of locking for us.

None of this makes a real difference in this particular patch, but it does
in other places where similar replacements are or have been made and we
want to be consistent in our usage of data structures in btrfs.

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.
