From bb4cb25213ce21326236d72e8633844e4a777a8b Mon Sep 17 00:00:00 2001
From: Ulrich Drepper <drepper@redhat.com>
Date: Thu, 14 Feb 2002 03:54:02 +0000
Subject: Update.

	* elf/dl-close.c (_dl_close): When closing an object using TLS
	either decrement dl_tls_max_dtv_idx or set dl_tls_dtv_gaps to
	true.  Increment dl_tls_generation only if we closed any TLS-using
	object.
	* elf/tst-tls6.c: New file.
	* elf/Makefile: Add rules to build and run tst-tls6.
