From b3c49d3df82466646bde9beebce7bbf0b3c41853 Mon Sep 17 00:00:00 2001 From: Richard Yao 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.
