These changes can be due to writes we make ourselves or due to changes made by the control domain. The goal of these changes is to insure that all state transitions can be detected regardless of their source and to allow common device policies (e.g. "onlined" backend devices) to be centralized in the XenBus bus code. sys/xen/xenbus/xenbusvar.h: sys/xen/xenbus/xenbus.c: sys/xen/xenbus/xenbus_if.m: Add a new method for XenBus drivers "localend_changed".

This notification cannot fail, so it should return void. sys/xen/xenbus/xenbusb_back.c: Add "online" device handling to the XenBus Back Bus support code. An online backend device remains active after a front-end detaches as a reconnect is expected to occur in the near future. sys/xen/interface/io/xenbus.h: Add comment block further explaining the meaning and driver responsibilities associated with the XenBus Closed state. sys/xen/xenbus/xenbusb.c: sys/xen/xenbus/xenbusb.h: sys/xen/xenbus/xenbusb_back.c: sys/xen/xenbus/xenbusb_front.c: sys/xen/xenbus/xenbusb_if.m: o Register a XenStore watch against the local XenBus tree for all devices. o Cache the string length of the path to our local tree. o Allow the xenbus front and back drivers to hook/filter both local and otherend watch processing. o Update the device ivar version of "state" when we detect a XenStore update of that node. sys/dev/xen/control/control.c: sys/xen/xenbus/xenbus.c: sys/xen/xenbus/xenbusb.c: sys/xen/xenbus/xenbusb.h: sys/xen/xenbus/xenbusvar.h: sys/xen/xenstore/xenstorevar.h: Allow clients of the XenStore watch mechanism to attach a single uintptr_t worth of client data to the watch.

An online backend device remains active after a front-end detaches as a reconnect is expected to occur in the near future. sys/xen/interface/io/xenbus.h: Add comment block further explaining the meaning and driver responsibilities associated with the XenBus Closed state. sys/xen/xenbus/xenbusb.c: sys/xen/xenbus/xenbusb.h: sys/xen/xenbus/xenbusb_back.c: sys/xen/xenbus/xenbusb_front.c: sys/xen/xenbus/xenbusb_if.m: o Register a XenStore watch against the local XenBus tree for all devices. o Cache the string length of the path to our local tree. o Allow the xenbus front and back drivers to hook/filter both local and otherend watch processing. o Update the device ivar version of "state" when we detect a XenStore update of that node. sys/dev/xen/control/control.c: sys/xen/xenbus/xenbus.c: sys/xen/xenbus/xenbusb.c: sys/xen/xenbus/xenbusb.h: sys/xen/xenbus/xenbusvar.h: sys/xen/xenstore/xenstorevar.h: Allow clients of the XenStore watch mechanism to attach a single uintptr_t worth of client data to the watch. This removes the need to carefully place client watch data within enclosing objects so that a cast or offsetof calculation can be used to convert from watch to enclosing object.
