Linux kernel source tree
2c5cca03c1
[BACKGROUND] Currently btrfs shares workspaces and their managers for all filesystems, this is mostly fine as all those workspaces are using page size based buffers, and btrfs only support block size (bs) <= page size (ps). This means even if bs < ps, we at most waste some buffer space in the workspace, but everything will still work fine. The problem here is that is limiting our support for bs > ps cases. As now a workspace now may need larger buffer to handle bs > ps cases, but since the pool has no way to distinguish different workspaces, a regular workspace (which is still using buffer size based on ps) can be passed to a btrfs whose bs > ps. In that case the buffer is not large enough, and will cause various problems. [ENHANCEMENT] To prepare for the per-fs workspace migration, add an fs_info parameter to all workspace related functions. For now this new fs_info parameter is not yet utilized. 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.
