This involves: - Add (alloc|free)_workspace_manager helpers. These are the helper to alloc/free workspace_manager structure. The allocator will allocate a workspace_manager structure, initialize it, and pre-allocate one workspace for it. The freer will do the cleanup and set the manager pointer to NULL. - Call alloc_workspace_manager() inside btrfs_alloc_compress_wsm() - Call alloc_workspace_manager() inside btrfs_free_compress_wsm() For none, zlib and lzo compression algorithms. For now the generic per-fs workspace managers won't really have any effect, and all compression is still going through the global workspace manager.

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.
