It basically removes it from architectures auto-generation list. Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32, arch64-linux-gnu, arm-linux-gnueabihf, powerpc64le-linux-gnu, sparc64-linux-gnu, and sparcv9-linux-gnu. * misc/makefile (CFLAGS-datasync.c): New flag. * nptl/makefile (CFLAGS-datasync.c): Likewise. * sysdeps/unix/sysv/linux/syscalls.list (fdatasync): Remove from auto-generation syscall list. * sysdeps/unix/sysv/linux/fdatasync.c: New file. --- ChangeLog | 6 ++++++ misc/Makefile | 1 + nptl/Makefile | 1 + sysdeps/unix/sysv/linux/fdatasync.c | 29 +++++++++++++++++++++++++++++ sysdeps/unix/sysv/linux/syscalls.list | 1 - 5 files changed, 37 insertions(+), 1 deletion(-) create mode 100644 sysdeps/unix/sysv/linux/fdatasync.c diff --git a/misc/Makefile b/misc/Makefile index 8536255..2f1ddef 100644 --- a/misc/Makefile +++ b/misc/Makefile @@ -109,6 +109,7 @@ CFLAGS-getusershell.c = -fexceptions CFLAGS-err.c = -fexceptions CFLAGS-tst-tsearch.c = $(stack-align-test-flags) CFLAGS-msync.c = -fexceptions +CFLAGS-fdatasync.c = -fexceptions # Called during static library initialization, so turn stack-protection # off for non-shared builds. diff --git a/nptl/Makefile b/nptl/Makefile index 875ab3d..879efbb 100644 --- a/nptl/Makefile +++ b/nptl/Makefile @@ -218,6 +218,7 @@ CFLAGS-read.c = -fexceptions -fasynchronous-unwind-tables CFLAGS-write.c = -fexceptions -fasynchronous-unwind-tables CFLAGS-nanosleep.c = -fexceptions -fasynchronous-unwind-tables CFLAGS-msync.c = -fexceptions -fasynchronous-unwind-tables +CFLAGS-fdatasync.c = -fexceptions -fasynchronous-unwind-tables CFLAGS-pt-system.c = -fexceptions diff --git a/sysdeps/unix/sysv/linux/fdatasync.c b/sysdeps/unix/sysv/linux/fdatasync.c new file mode 100644 index 0000000..09a07fb --- /dev/null +++ b/sysdeps/unix/sysv/linux/fdatasync.c @@ -0,0 +1,29 @@ +/* Synchronize a file's in-core state with storage device Linux + implementation. + Copyright (C) 2017 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.
