Merge branch 'for-linus' of git://git.samba.org/sfrench/cifs-2.6 

Pull cifs fixes from Steve French:
 "A few small cifs fixes including two for stable, and fixing a
  regression introduced by the VFS change to file create"

* 'for-linus' of git://git.samba.org/sfrench/cifs-2.6:
  cifs: set FILE_CREATED
  cifs: We do not drop reference to tlink in CIFSCheckMFSymlink()
  Add missing end of line termination to some cifs messages
