NAME
       idr_destroy - release all cached layers within an idr tree

SYNOPSIS
       void idr_destroy(struct idr * idp);

ARGUMENTS
       idp
	   idr handle

DESCRIPTION
       Free all id mappings and all idp_layers. After this function, idp is
       completely unused and can be freed / recycled. The caller is
       responsible for ensuring that no one else accesses idp during or after
       idr_destroy.

       A typical clean-up sequence for objects stored in an idr tree will use
       idr_for_each to free all objects, if necessay, then idr_destroy to free
       up the id mappings and cached idr_layers.
