Is xenballoond still maintained?

http://lxr.xensource.com/lxr/source/tools/xenballoon/xenballoond still
use "echo $tgtbytes > /proc/xen/balloon", while /proc/xen/balloon does
not exists in pv_ops kernel. There's
/sys/devices/system/xen_memory/xen_memory0/target_kb , which seems to
work as expected, so it might be a simple matter of adding a test to
choose which file to write memory target to.

Also, when writing a number lower than initial value to
/sys/devices/system/xen_memory/xen_memory0/target_kb, "xm list" on
dom0 still shows old memory value, but "xm info" correctly shows some
memory freed. This is different with "xm mem-set" from dom0, which
correctly updates both values.
