NAME
       idr_get_new_above - allocate new idr entry above or equal to a start id

SYNOPSIS
       int idr_get_new_above(struct idr * idp, void * ptr, int starting_id,
			     int * id);

ARGUMENTS
       idp
	   idr handle

       ptr
	   pointer you want associated with the id

       starting_id
	   id to start search at

       id
	   pointer to the allocated handle

DESCRIPTION
       This is the allocate id function. It should be called with any required
       locks.

       If allocation from IDR's private freelist fails, idr_get_new_above will
       return -EAGAIN. The caller should retry the idr_pre_get call to refill
       IDR's preallocation and then retry the idr_get_new_above call.

       If the idr is full idr_get_new_above will return -ENOSPC.

       id returns a value in the range starting_id ...	0x7fffffff
