commit 1ee1218e3f9b6eda8bc07303027158a4f660fdab
Author: Joseph Myers <joseph@codesourcery.com>
Date:   Wed Oct 21 23:37:02 2015 +0000

    Move io/tst-fcntl temporary file creation to do_prepare.
    
    This patch makes the io/tst-fcntl test create its temporary file in
    do_prepare not do_test, so that add_temp_name is called in the parent
    on the correct file name, as requested in the thread starting at
    <https://sourceware.org/ml/libc-alpha/2015-10/msg00552.html>.  I don't
    see any reason in this test that opening the file in the parent should
    be problematic.
    
    This patch is explicitly not exhaustive for such issues; other tests
    still call add_temp_file in the child.  The general issue is noted at
    <https://sourceware.org/glibc/wiki/Development_Todo/Master#Use_test-skeleton.c>.
    
    Tested for x86_64 (that this test still passes and no longer leaves a
    file behind in /tmp).
    
    	* io/tst-fcntl.c (fd): New static variable.
    	(do_prepare): Open temporary file here....
    	(do_test): ...not here.
