samba - Jul 2014 - Using SMB_VFS_IS_OFFLINE for directories.

I made a small change to source3/smbd/dosmode.c to let my plugin on my 
linux box return FILE_ATTRIBUTE_OFFLINE for directories, and so far 
Windows (2008) seems okay with it.  It displays the folder icon with the 
"X" over it and it navigates the folder hierarchy without trouble (so
far).

I can see that the SMB_VFS_IS_OFFLINE code went in originally for DMAPI 
support (Bokovoy, Jan 2008, commit d86fc3ec) and that DMAPI doesn't have 
the concept of punching a directory like it does for files.  So that 
would explain the limitation in the original code.

But, has anyone used this for directories?

Not that I know of. Can you post your patch so
we can take a look ?

Do you have any test code that will allow us to
ensure this doesn't break anything (preferably
something that runs against Windows first :-) ?
