It seems that it?s worth trying LZ4 compressed kernel image or ramdisk
for making the kernel boot more faster.

There's another potential user of lz4: btrfs. I've submitted a feature
preview integrating lz4 compression
http://thread.gmane.org/gmane.comp.file-systems.btrfs/15744
and we have tried to integrate the HC mode as well
http://thread.gmane.org/gmane.comp.file-systems.btrfs/18165
.
So far it's on a slow track, conceptually it works, but I the code needs
some work so it could live under lib/* (we've used the svn sources with
minor changes, no kernel coding style). It would be easier for me to
enhance the existing lib/lz4/* codebase.

I don't know much about btrfs. But I guess the lz4 related APIs should
be migrated and integrated under lib/lz4/* like the way lzo implemented.

Also zram could consider lz4, I'm not sure if there are other potential
users.
