The thread started on 26 Jan 2013. Thanks. https://lkml.org/lkml/2013/1/29/145 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. http://linux-kernel.2935.n7.nabble.com/GIT-PULL-Update-LZO-compression-code-for-v3-9-td605184.html
