[PATCH] alpha: drop __ASSUME_FDATASYNC
- From: Mike Frysinger <vapier at gentoo dot org>
- To: libc-alpha at sourceware dot org
- Cc: rth at twiddle dot net

- Subject: [PATCH] alpha: drop __ASSUME_FDATASYNC
- Authentication-results: sourceware.org; auth=none
Since we require a new enough kernel all the time, the __ASSUME_FDATASYNC
define has been hardcoded to 1. That means we can delete the alpha file
for fdatasync now and rely on the syscalls list like other ports.

* sysdeps/unix/sysv/linux/alpha/Makefile (CFLAGS-fdatasync.c): Delete.
* sysdeps/unix/sysv/linux/alpha/fdatasync.c: Delete.
* sysdeps/unix/sysv/linux/alpha/kernel-features.h
(__ASSUME_FDATASYNC): Delete.
