## NAME

idr\_remove\_all - remove all ids from the given idr tree

## SYNOPSIS

**void idr\_remove\_all(struct idr \*** *idp***);**

## 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.
