From b3c49d3df82466646bde9beebce7bbf0b3c41853 Mon Sep 17 00:00:00 2001
From: Richard Yao <ryao@gentoo.org>
Date: Sat, 5 Oct 2013 17:55:24 -0400
Subject: [PATCH] Linux 3.11 compat: Rename LZ4 symbols
Linus Torvalds merged LZ4 into Linux 3.11. This causes a conflict
whenever CONFIG_LZ4_DECOMPRESS=y or CONFIG_LZ4_COMPRESS=y are set in the
kernel's .config. We rename the symbols to avoid the conflict.
Signed-off-by: Richard Yao <ryao@gentoo.org>
Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov>
Closes #1789
