This is the v10 patch for ndctl monitor, a tiny daemon to monitor
the smart events of nvdimm DIMMs. Since NVDIMM does not have a
feature like mirroring, if it breaks down, the data will be
impossible to restore. Ndctl monitor daemon will catch the smart
events notify from firmware and outputs notification to logfile,
therefore users can replace NVDIMM before it is completely broken.
