NAME
       idr_remove_all - remove all ids from the given idr tree

SYNOPSIS
       void idr_remove_all(struct idr * idp);

ARGUMENTS
       idp
	   idr handle

DESCRIPTION
       idr_destroy only frees up unused, cached idp_layers, but this function
       will remove all id mappings and leave all idp_layers unused.

       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_remove_all to
       remove all ids, and idr_destroy to free up the cached idr_layers.
