From 508e0893686794be55cfaa336fea584b16a471d9 Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Sat, 17 Apr 2010 10:49:07 +0100 Subject: [PATCH] qcow2: Avoid shadowing variable in alloc_clusters_noref() The i loop iterator is shadowed by the next free cluster index. Both using the variable name 'i' makes the code harder to read.
