[linux-cifs-client] chmod on a cifs client and ACLs on a Windows server

[Steven French]

The alternative behavior would be that all ACEs are preserved, except 
those for owner, owning group (if present), and everyone (those three 
would be overwritten by the mode bits).

The current behavior for chmod on the Linux cifs client works on mounts 
that are mounted with the "cifsacl" mount option in the current Linux cifs 
development tree (and presumably in -mm by now) but is not checked into 
mainline kernel yet - but we want to resolve the right behavior before 
2.6.25 builds open up in a few weeks (so that this could can make 2.6.25).

Cifs client, when chmod command is issued, follows what
SFU/Interix does.  Is this the behaviour that cifs client
should exhibit (that is how it is implemented currently)?

When doing a chmod on Interix, always the following is done:
- all ACLs are removed and replaced by 3 new ACLs,
  one for the windows file owner, one for the POSIX group of the
  file owner and one for Everyone (SSID: S-1-1-0)

Shirish
