[Xen-devel] [PATCH v2 3/4] freemem: remove call to libxl_wait_for_free_memory

[Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx>]

Now that libxl_wait_for_memory_target is capable of waiting until dom0
reaches its target, we can remove the other wait function call:
libxl_wait_for_free_memory. No need to wait twice. Once dom0 has met its
target, simply loop again and recalculate free_memkb.
