From 4e633572ef8a9b07d1ae1252cf4c2b2daf673998 Mon Sep 17 00:00:00 2001

Subject: [PATCH] disable emulate_legacy_capacity on creating RBD backstore
When rbd image has object-map feature set, `enable` will fail
unless emulate_legacy_capacity (default is 1) is set to 0.
Provide a possibility to disable emulate_legacy_capacity when
creating backstore (before enabling it) via additional
disable_emulate_legacy_capacity parameter.
We might eventually want to merge the rbd support patches into one,
but right now keeping them separate looks useful for tracking the
change (feature) added here.
This patch is for the changes added by "rbd support" patch
(rbd-support.patch) and thus it is not needed upstream until
the rbd support is added upstream.
Eventualy we might want to merge this and "rbd support" patches
into one. For now it looks useful to keep it separate to track
the change (feature) added by this patch.
ceph-iscsi needs this change to support rbd images with
object-map feature enabled.
