I want a way that a backup app (or any linux app for that matter) could 
get at -
1) the create time
2) the dos attributes

The protocol gives these to me in QPathInfo anyway (which e.g. is called 
for lookup / getattr).

When I am mounted to Windows (or Samba or any cifs box for that matter) I 
have these in my cifs vfs specific part of the local inode, so why not 
make it possible for a local Linux app to view them?  I don't ever plan to 
send queries to Samba server for user.DosAttrib (that would make no sense 
- SMB QPathInfo is faster).

Since various Linux local filesystems such as JFS and NTFS (and VFAT etc.) 
also have fields in their on disk format for these it seems sensible that 
they would also special case user.DosAttrib and return to apps that ask.
