Subject: [PATCH 7/7] zram: mark the disk as non-rotating media
Date: Wed, 26 Jan 2011 11:27:44 -0600	[thread overview]
Message-ID: <20110126172743.GI8446@linux.vnet.ibm.com> (raw)
In-Reply-To: <20110126172148.GB8446@linux.vnet.ibm.com>

Adding QUEUE_FLAG_NONROT for the in the request_queue flags.  When used
as a swap device, scan_swap_map will avoid the extra work of optimizing
for rotating media.
