There are two levels of workspace management. First, alloc()/free() which are responsible for actually creating and destroy workspaces. Second, at a higher level, get()/put() which is the compression code asking for a workspace from a workspace_manager. The compression code shouldn't really care how it gets a workspace, but that it got a workspace. This adds get_workspace() and put_workspace() to be the higher level interface which is responsible for indexing into the appropriate compression type. It also introduces btrfs_put_workspace() and btrfs_get_workspace() to be the generic implementations of the higher interface.

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.
