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. --- NEWS | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'NEWS') diff --git a/NEWS b/NEWS index 363e918da1..5155c86318 100644 --- a/NEWS +++ b/NEWS @@ -59,6 +59,10 @@ Deprecated and removed features, and other changes affecting compatibility: * The tilegx*-*-linux-gnu configurations are no longer supported. +* The obsolete function ustat is no longer available to newly linked + binaries; the headers and have been removed.
