Synchronizing Access to Resources › Resource Name Hierarchy

Resource Name Hierarchy

Specific resource names, that is, those that are explicitly defined by primary and minor name, are peers within their resource group.

Any process that obtains exclusive control of the resource CONFIG prevents any other process in the system from gaining access to any other resource below CONFIG in the hierarchy. Therefore no process can gain access to the CONFIG.XYZ resource, until the first process releases its exclusive control of the CONFIG resource lock.

Alternatively, a process that requests exclusive control of the CONFIG.ABC resource does not prevent any other process from accessing the CONFIG.XYZ resource.
