Hello, Nick.

Awesome work!!!

Let me ask a question.
Zram compress and decompress a small data (a page) and your github
site says that using predefined dictionary would be helpful in this
situation. However, it seems that compression crypto API for zstd
doesn't use ZSTD_compress_usingDict(). Is there any plan to support
it?

Thanks.
