hello,
(sorry google translation)

I mount shares with the following command:

mount -t cifs //${HOST}/${DIR} /run/media/${USER}/${HOST}/${DIR} -o credentials=/etc/smbpasswd

I use the following code example to test reading the contents of the mount point.
http://www.kernel.org/doc/man-pages/online/pages/man2/getdents.2.html
(gcc version 4.7.2 (GCC) Modèle de thread: posix)

But the result shows that lack of information, it seems that between each call syscal_getdents there is a problem.

if I reduce the size "BUFFER" there is a larger number of iteration shows that each iteration we lose information.

If I mounted shares with gvfs
gvfs-mount smb :/ / $ {HOST} / $ {DIR}
the result is correct.

My question: is it the problem with cifs?
