Adhemerval Zanella cf2478d53a 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.		2018-05-02 08:43:31 -03:00
