Please verify that it indeed does not change the code. Feel free to commit it yourself if you want to, or I'll do it on your approval. What I use to verify no code changes is: $ make -j... # build before applying patch $ mkdir =stock $ cp libc.so =stock/ ... apply the patch ... $ make -j... # build after applying patch $ diff -u -I '.*file format.*' <(objdump -rd =stock/libc.so) <(objdump -rd libc.so) Thanks, Roland * sysdeps/unix/sysv/linux/s390/arch-fork.h: New file. * nptl/sysdeps/unix/sysv/linux/s390/fork.c: File removed. --- a/nptl/sysdeps/unix/sysv/linux/s390/fork.c +++ /dev/null @@ -1,30 +0,0 @@ -/* Copyright (C) 2003-2014 Free Software Foundation, Inc. - This file is part of the GNU C Library. - Contributed by Martin Schwidefsky , 2003. - - The GNU C Library is free software; you can redistribute it and/or - modify it under the terms of the GNU Lesser General Public - License as published by the Free Software Foundation; either - version 2.1 of the License, or (at your option) any later version. - - The GNU C Library is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
