[linux-cifs-client] still problems ..

[Gorazd Golob]

Hi!

I still have problems with coping data (~50gb in ~100mb files) from samba
server 3.0.7 from mount point with direct option. Here are
/proc/fs/cifs/DebugData and /proc/fs/cifs/Stats after the lock. I can't
access mountd points in any possible way..
Note: There are 4 different servers with same configuration
