Suspicious RLIM_INFINITY use, 2.4.17

[(no name)]

Hi,

I came acros this (2.4.17):

fs/binfmt_aout.c:

	rlim = current->rlim[RLIMIT_DATA].rlim_cur;
	if (rlim >= RLIM_INFINITY)
		rlim = ~0;
	if (ex.a_data + ex.a_bss > rlim)
		return -ENOMEM;

this looks like it will disable any limit checks, but no similar
code is binfmt_elf so maybe it should be removed altogether?
