Re: sendmail "cannot fsync directory" after 2.4 -> 2.6

[Frank Steiner <fsteiner-mail@bio.ifi.lmu.de>]

I wrote a little c program to test fsync on nfs directories (must be
called in the directory you want to check):

#include <fcntl.h>

int main() {
int dirfd;
dirfd = open(".",O_RDONLY, 0700);
if (fsync(dirfd) < 0)
   printf("failed\n");
else
   printf("succeeded\n");
}


Indeed it fails for all nfs-mounted directories when the client is running
kernel 2.6 (tried 2.6.6 and 2.6.8.1), and succeeds for clients running
kernel 2.4, with the same nfs server (regardless if the server is running
2.6 or 2.4).

cu,
Frank
