extent-tree.c has a find_next_key that just walks up the path to find the next key, but it is used for both the caching stuff and the snapshot delete stuff. The snapshot deletion stuff is special so it can't really use btrfs_find_next_key, but the caching thread stuff can. We just need to fix btrfs_find_next_key to deal with ->skip_locking and then it works exactly the same as the private find_next_key helper.

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.
