A file system that fundamentally only supports subfiles could tell  
the VFS layer "I don't support extattrs" by any number of  
mechanisms.  The VFS layer could then simulate extattrs using  
specially-named subfiles.  This is not all that different from how  
extattrs are currently "supported" on UFS1 file systems (I will admit  
that the code that does this is a work-in-progress that needs to be  
greatly improved upon -- but it's a start!)
