From 8bf1bb4bf1c7a58f9f9b64f599ed5a8eaeefe3a6 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Sun, 26 Jul 2009 15:17:21 -0400 Subject: enable nanosecond stat support for everyone Fill out the stat structure so that the nanosecond resolution support is always available. There is a small code size increase for a few ports (three additional assignments in xstatconv), but otherwise everything should remain the same. While we're here, punt __old_kernel_stat from the few headers that still define it as it is unused in uClibc and causes compile errors after these nanosecond changes.
