Linux kernel source tree

There are several interfaces involved for each algorithm: - alloc workspace All algorithms allocate a workspace without the need for workspace manager. So no change needs to be done. - get workspace This involves checking the workspace manager to find a free one, and if not, allocate a new one. For none and lzo, they share the same generic btrfs_get_workspace() helper, only needs to update that function to use the per-fs manager. For zlib it uses a wrapper around btrfs_get_workspace(), so no special work needed. For zstd, update zstd_find_workspace() and zstd_get_workspace() to utilize the per-fs manager. - put workspace For none/zlib/lzo they share the same btrfs_put_workspace(), update that function to use the per-fs manager. For zstd, it's zstd_put_workspace(), the same update. - zstd specific timer This is the timer to reclaim workspace, change it to grab the per-fs workspace manager instead. Now all workspace are managed by the per-fs manager. Signed-off-by: Qu Wenruo <wqu@suse.com> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com> |

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.
