Right now we are using a struct btrfs_backref_shared_cache to pass state across multiple btrfs_is_data_extent_shared() calls. The structure's name closely follows its current purpose, which is to cache previous checks for the sharedness of metadata extents. However we will start using the structure for more things other than caching sharedness checks, so rename it to struct btrfs_backref_share_check_ctx.

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.
