Nope, only on ext4.

vboxsf:

1358485717.265985900 fstat
1358485717.265985900 lstat
1358485717.265985900 stat

1358485717.265985900 fstat
1358485717.265985900 lstat
1358485717.265985900 stat

cifs:

1358485764.638001400 fstat
1358485764.638001400 lstat
1358485764.638001400 stat

1358485764.638001400 fstat
1358485764.638001400 lstat
1358485764.638001400 stat

ext4 (just for completeness):

1358485649.211315918 fstat
1358485649.211315918 lstat
1358485649.211315918 stat

1358485649.223315921 fstat
1358485649.223315921 lstat
1358485649.223315921 stat

Ran it quite a few times, the results were always identical.
