NAME
       idr_pre_get - reserve resources for idr allocation

SYNOPSIS
       int idr_pre_get(struct idr * idp, gfp_t gfp_mask);

ARGUMENTS
       idp
	   idr handle

       gfp_mask
	   memory allocation flags

DESCRIPTION
       This function should be called prior to calling the idr_get_new*
       functions. It preallocates enough memory to satisfy the worst possible
       allocation. The caller should pass in GFP_KERNEL if possible. This of
       course requires that no spinning locks be held.

       If the system is REALLY out of memory this function returns 0,
       otherwise 1.
