Subject: [RHEL5][PATCH] CIFS: invalids readdires

When a directory with over 100 files is mounted
using CIFS, an ls of that directory fails with an
"Invalid argument" error.

The attached patch is from bz211070 and was originally authored by
the CIFS upstream maintainer... but I was able to reproduce this
problem, so I too can verify the patch does indeed fix the problem.

The bz is:
