While replaying log trees we need to do searches and updates to subvolume trees and for that we use a path that we allocate in replay_one_buffer() and then pass it as a parameter to other functions deeper in the log replay call chain. Instead of passing it as parameter, add it to struct walk_control since we pass a pointer to that structure for every log replay function. This reduces the number of arguments passed to the functions and it will be needed and important for an upcoming changes that improves error reporting for log replay. Also name the new filed in struct walk_control to 'subvol_path' - while that is longer to type, the naming makes it clear it's used for subvolume tree operations since many of the log replay functions operate both on subvolume and log trees, and for the log tree searches we have struct walk_control::log_leaf to also make it obvious it's an extent buffer for a log tree extent buffer.

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 reStructuredText 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.
