CIFS mounted drive issue

[Yegor Yefremov]

I have problems making "ls -l /mnt" on CIFS mounted drives. Instead of
file listing I get following error: Value too large for defined data
type.

My system is:

CPU: ARM9 ks8695
kernel 2.6.32/33
uClibc 0.9.27

I had no problems with the same uClibc and kernel 2.6.26. I have also
tried openwrt with uClibc 0.9.30.1/2, but with the same result: ls -l
fails.

Large File Support was enabled in both uClibc and busybox. I even
tried non busybox ls, but with the same result.

The same kernel make no problem with ARM Debian.

I think it has something to do with fstat call. Please compare strace
outputs from uCliux and Debian.

uClinux:

Any idea?
