Subject: [PATCH v2] kvm tools: remove redundant "if" condition
Date: Wed, 16 Jan 2013 17:52:40 +0100 [thread overview]
Message-ID: <20130116165239.GB18593@gmail.com> (raw)
In-Reply-To: <20130116113522.GR11529@redhat.com>
After we check (state.kcount != 0), state.kcount has to be 0 in all the "else"
branchs.
