I did not and do not see significant value in
adding LZ4 given Markus' LZO improvements.
I asked about LZO.
Why would the LZO code not be updated?
The new LZO code is faster than ever and it's
a standalone improvement.
Markus has posted what seems a clean git pull
request. It was not cc'd to arm or linux-arch.
