31 + * Zero-length encoding. This is a fast and simple algorithm to eliminate
32 + * runs of zeroes. Each chunk of compressed data begins with a length byte, b.
33 + * If b < n (where n is the compression parameter) then the next b + 1 bytes
34 + * are literal values. If b >= n then the next (256 - b + 1) bytes are zero.
i`m curious - what does that mean?
does zfs have another compression scheme named "zle" now ?
if yes, why ?
wasn´t zero-length encoding already there and just a "builtin feature" ?
