You do consistently ask for a shim layer, but you haven’t explained 
what we gain by diverging from the documented and tested API of the 
upstream zstd project.  It’s an important discussion given that we 
hope to regularly update the kernel side as they make improvements in 
zstd.

The only benefit described so far seems to be camelcase related, but if 
there are problems in the API beyond that, I haven’t seen you describe 
them.  I don’t think the camelcase alone justifies the added costs of 
the shim.
