From 98f531da8479eec3d828adc7f0865baaab99a543 Mon Sep 17 00:00:00 2001 From: Igor Mammedov Date: Tue, 2 Aug 2011 11:45:25 +0200 Subject: [PATCH] xen: Fix misleading WARN message at xen_release_chunk WARN message should not complain "Failed to release memory %lx-%lx err=%d\n" ^^^^^^^ about range when it fails to release just one page, instead it should say what pfn is not freed. In addition line: printk(KERN_INFO "xen_release_chunk: looking at area pfn %lx-%lx: " ... printk(KERN_CONT "%lu pages freed\n", len); will be broken if WARN in between this line is fired. So fix it by using a single printk for this.
