I think d_inode() is better. They work the same, but "normal filesystems should not use this", according to the d_backing_inode() documentation.
Right, definitely. I copied it from vfs_getattr_nosec() without thinking about it much. I see how David Howells put that d_backing_inode() there, but still don't understand it.

What about symlinks and special files?
My mistake again, thanks for pointing that out. Doing the symlinks correctly here would actually add a bit more complexity as they use the generic page_symlink_inode_operations at the moment.
I think I'd rather just retract this patch and let someone else handle it if they actually want this feature. I only added it because it seemed trivial to do, but that was clearly not true. ;-)
