Did vboxsf and/or cifs report time stamps that
were not on 100-ns boundaries? That would be a bug.
How about the following program? What does it output?
#include <fcntl.h>
#include <sys/stat.h>
#include <stdio.h>
#include <unistd.h>
#include <time.h>
static int
report_times (int fd, char const *file)
{
struct stat fst, lst, st;
if (fstat (fd, &fst) != 0)
return perror ("fstat"), -1;
if (lstat (file, &lst) != 0)
return perror ("lstat"), -1;
if (stat (file, &st) != 0)
return perror ("stat"), -1;
printf ("%ld.%09ld fstat\n", (long) fst.st_mtim.tv_sec, fst.st_mtim.tv_nsec);
printf ("%ld.%09ld lstat\n", (long) lst.st_mtim.tv_sec, lst.st_mtim.tv_nsec);
printf ("%ld.%09ld stat\n", (long) st.st_mtim.tv_sec, st.st_mtim.tv_nsec);
printf ("\n");
return 0;
}
int
main (void)
{
static char const file[] = "foo";
struct timespec interval;
int fd;
unlink (file);
fd = open (file, O_CREAT | O_WRONLY, -1);
if (fd < 0)
return perror ("open"), 1;
if (report_times (fd, file) != 0)
return 1;
interval.tv_sec = 0;
interval.tv_nsec = 10000000;
if (nanosleep (&interval, 0) != 0)
return perror ("nanosleep"), 1;
if (write (fd, file, sizeof file - 1) != sizeof file - 1)
return perror ("write"), 1;
if (report_times (fd, file) != 0)
return 1;
return 0;
}
