Detailed Description

Represents a resource identity (i.e., a name). Multiple copies of the same name may exist in different resource management domains, but no more than a single copy per domain.

m0_rm_resource is allocated and destroyed by the appropriate resource type. An instance of m0_rm_resource would be typically embedded into a larger resource type specific structure containing details of resource identification.

Generic code uses m0_rm_resource to efficiently compare resource identities.
