From e7b9b550f53e81ea38e71d322d6f95730df058a2 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Sun, 29 Mar 2009 16:31:16 -0400 Subject: [PATCH] Don't mess with descriptor table in load_elf_binary() ... since we don't tell anyone which descriptor does the file get. We used to, but only in case of ELF binary with a.out loader and that stuff has been gone for a while.
