/*
* Each general-purpose state structure is named by an FMRI - the FMRI of the
* piece of hardware being described. FMRIs are nvlists, and thus require
* special handling if they are to be persisted along with the general-purpose
* buffer. The gmem_fmri_t manages the FMRI, both in packed (persistable) and
* unpacked formats. The packed FMRI is stored in a separate buffer (named by
* the fmri_packnm member), from which it can be unpacked on restore.
*
* Data structures:
*

* ||fmri_t | ----> |packed nvlist|
* |`-------| `-------------'
* `--------'
*
* The buffer for the general purpose buffer is named and stored independently.
* This subsystem creates and manages the packed nvlist buffer, using a name
* provided by the caller.
