From 3ac51e741a46af7a20f55e79d3e3aeaa93c6c544 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Mon, 27 Mar 2006 01:17:54 -0800 Subject: [PATCH] dm store geometry Allow drive geometry to be stored with a new DM_DEV_SET_GEOMETRY ioctl. Device-mapper will now respond to HDIO_GETGEO. If the geometry information is not available, zero will be returned for all of the parameters. Signed-off-by: Darrick J.
