The patchset has been added to msic-next, scheduled for 5.1. I've left
out the changes to warn on wrong level, so currently it falls back to
the default. I don't want to make a last minute change of that sort, so
this needs to go as a separate patch.

I also did a last pass through all patches and made some trivial changes
like reformatting comments or minor style updates, nothing functional.
The inter-branch diff can be found at
https://github.com/kdave/btrfs-devel/compare/ext/dzhou/compr-workspaces-v2..kdave:ext/dzhou/compr-workspaces

The feature should be ready to use, though as mentioned before some fine
tuning might be necessary to make the memory requirements more
efficient. The code could be simplified or cleaned up now that there are
3 compressors, at this point stabilization fixes are preferred.

Thanks.
