With <a href="https://jira.whamcloud.com/browse/LU-15092" class="external-link" rel="nofollow">https://jira.whamcloud.com/browse/LU-15092</a> this causes an interop issue because FMR/FastReg may be needed to map the higher fragment count. We should change the default map_on_demand to 1 so that FMR/FastReg is used by default. map_on-demand can still be set to 0 if needed.</p> LU-15186
