From 8ad81b316bc158746aee18aa7d7df44d3eb61871 Mon Sep 17 00:00:00 2001 From: Jakub Jelinek Date: Tue, 17 Nov 2009 18:04:51 -0800 Subject: Fix sync_file_range on ppc/ppc64. I've noticed that sync_file_range is a stub on ppc/ppc64. The kernel on these arches provides sync_file_range2 syscall with swapped parameters. The following completely untested patch ought to fix this. --- .../sysv/linux/powerpc/powerpc64/sync_file_range.c | 44 ++++++++++++++++++++++ 1 file changed, 44 insertions(+) create mode 100644 sysdeps/unix/sysv/linux/powerpc/powerpc64/sync_file_range.c (limited to 'sysdeps/unix/sysv/linux/powerpc/powerpc64') diff --git a/sysdeps/unix/sysv/linux/powerpc/powerpc64/sync_file_range.c b/sysdeps/unix/sysv/linux/powerpc/powerpc64/sync_file_range.c new file mode 100644 index 0000000000..1ca4ce66df --- /dev/null +++ b/sysdeps/unix/sysv/linux/powerpc/powerpc64/sync_file_range.c @@ -0,0 +1,44 @@ +/* Selective file content synch'ing. + Copyright (C) 2006, 2007, 2009 Free Software Foundation, Inc. + This file is part of the GNU C Library. + + 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.
