There is no enum for "NONE". If there is no persistence domain specified, then it is undefined/unknown, which results in the message: nd_pmem namespace0.0: unable to guarantee persistence of writes Other than that, yes, that's right. -Jeff _______________________________________________ Linux-nvdimm mailing list -- linux-nvdimm@lists.01.org To unsubscribe send an email to linux-nvdimm-le...@lists.01.org
