I agree with Rob; as much as possible, this should be done at the VFS level. The problem is that there will need to be at least some support in the individual file system, since there isn't a good place for the VFS to intercept the internal file system iget() function to patch in the override uid/gid values. So the question at this point is whether it's cleaner to have the functionality split between the VFS and the file system layers (i.e., with the options parsing and storing the override uid/gid values in the super_block structure) or keeping it all in the file system layer, and accepting the duplication of code across multiple file systems. My preference leans towards the former (pushing as much as we can into the VFS layer), but I can see the other point of view.
