Subject: [Qemu-devel] [PATCH 10/18] qcow2: Avoid shadowing variable in alloc_clusters_noref()
Date: Fri, 30 Apr 2010 16:00:32 +0200 [thread overview]
Message-ID: <1272636040-17374-11-git-send-email-kwolf@redhat.com> (raw)
In-Reply-To: <1272636040-17374-1-git-send-email-kwolf@redhat.com>
From: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>
The i loop iterator is shadowed by the next free cluster index. Both
using the variable name 'i' makes the code harder to read.
