IDR_DESTROY(9)                    Basic Kernel Library Functions                   IDR_DESTROY(9)



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 necessary, then idr_destroy to free up the id mappings and cached
       idr_layers.
