From 51fa8d8e2892d10981fb4f70e24789aea3b4385c Mon Sep 17 00:00:00 2001 From: Peter Korsgaard Date: Fri, 13 Oct 2017 21:16:52 +0200 Subject: [PATCH] fs/common.mk: support lz4 compression Similar to the other compressors. Notice that we use the -l (legacy format) for Linux kernel initrd compatibility. Lz4 decompression is supported by the Linux kernel since 3.11.
