From df6329d2eb252866542b9efaef34b2e0d777e649 Mon Sep 17 00:00:00 2001 From: Dwight Engen Date: Thu, 30 Oct 2014 15:55:35 -0400 Subject: [PATCH] sunvdc: don't call VD_OP_GET_VTOC [ Upstream commit 85b0c6e62c48bb9179fd5b3e954f362fb346cbd5 ] The VD_OP_GET_VTOC operation will succeed only if the vdisk backend has a VTOC label, otherwise it will fail. In particular, it will return error 48 (ENOTSUP) if the disk has an EFI label. VTOC disk labels are already handled by directly reading the disk in block/partitions/sun.c (enabled by CONFIG_SUN_PARTITION which defaults to y on SPARC). Since port->label is unused in the driver, remove the call and the field. Signed-off-by: Dwight Engen Signed-off-by: David S.
