which properly represents the maximum bit size of compressed literals (11) as defined in the specification.

To be preferred from HUF_TABLELOG_DEFAULT which represents the same value but by accident.

Name selected to keep the same convention as existing width definitions,
MLFSELog, LLFSELog and OffFSELog.
