Subject: [PATCH 09/20] Btrfs: skip allocation attempt from empty cluster
Date: Sun, 27 Nov 2011 00:05:09 -0200 [thread overview]
Message-ID: <215228eef80c9bd7e268a9f7a98c87573a15d005.1322507825.git.oliva@lsd.ic.unicamp.br> (raw)
In-Reply-To: <cover.1322507825.git.oliva@lsd.ic.unicamp.br>
If we don't have a cluster, don't bother trying to allocate from it,
jumping right away to the attempt to allocate a new cluster.
