This is required for any kernel prior to 2.6.19, since <linux/magic.h> didn't exist back then. Now that file is provided by the kernel-headers package. >From d14ef1669968ffeb65076b007e318934ed99aa61 Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering@xxxxxxxxxx> Date: Mon, 17 May 2010 16:17:08 +0200 Subject: [PATCH] build: avoid compile failure on linux kernels older than 2.6.19 * configure.ac: Check for <linux/magic.h>. * src/util/storage_file.c: Include <linux/magic.h> only if present. Linux kernels prior to 2.6.19 lacked it.
