From cf2478d53ad7071e84c724a986b56fe17f4f4ca7 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Sun, 18 Mar 2018 11:28:59 +0800 Subject: Deprecate ustat syscall interface As for sysctl, ustat has been deprecated in favor of {f}statfs. Also some newer ports which uses generic interface builds a stub version that returns ENOSYS. This patch deprecates ustat interface by removing ustat.h related headers, adding a compatibility symbol, and avoiding new ports to build and provide the symbol. Checked on x86_64-linux-gnu and i686-linux-gnu. Also checked with a check-abi on all affected ABIs. * NEWS: Add ustat.h deprecation entry. * bits/ustat.h: Remove file. * misc/sys/ustat.h: Likewise. * misc/ustat.h: Likewise. * sysdeps/unix/sysv/linux/generic/ustat.c: Likewise. * misc/Makefile (headers): Remove ustat.h and sys/ustat.h. * misc/ustat.c (__ustat): Rename to __old_ustat and export only in compatibility mode. * sysdeps/unix/sysv/linux/ustat.c (__ustat): Likewise. * sysdeps/unix/sysv/linux/mips/ustat.c: Define DEV_TO_KDEV and use generic Linux implementation. --- sysdeps/unix/sysv/linux/generic/ustat.c | 32 -------------------------------- 1 file changed, 32 deletions(-) delete mode 100644 sysdeps/unix/sysv/linux/generic/ustat.c (limited to 'sysdeps/unix/sysv/linux/generic') diff --git a/sysdeps/unix/sysv/linux/generic/ustat.c b/sysdeps/unix/sysv/linux/generic/ustat.c deleted file mode 100644 index d4f9c89..0000000 --- a/sysdeps/unix/sysv/linux/generic/ustat.c +++ /dev/null @@ -1,32 +0,0 @@ -/* Copyright (C) 2011-2018 Free Software Foundation, Inc. - This file is part of the GNU C Library. - Contributed by Chris Metcalf , 2011. - - 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.
