4.2.8-ckt5 -stable review patch. If anyone has any objections, please let me know. ---8<------------------------------------------------------------ From: Juergen Gross <jgross@xxxxxxxx> commit f285aa8db7cc4432c1a03f8b55ff34fe96317c11 upstream. When adding a new frontend to xen-scsiback don't decrement the number of active frontends in case of no error. Doing so results in a failure when trying to remove the xen-pvscsi nexus even if no domain is using it.
