There's another way to deal with this in NFS and fuse, without having to change the API:
- remove suid/sgid bits from i_mode, when refreshing the inode attributes - store the removed bits (or the original mode) in the fs' inode strucure - in ->getattr() restore the original mode into the returned stat This way the VFS believes, that the inode does not in fact have the suid/sgid bits and so won't call ->setattr() unnecessarily. I've tested a similar change in fuse for working around unneeded check for the directory sticky bit. Yes, this is cheating the interface, but there's a deeper level where it makes sense: the VFS should not be checking _any_ inode attribute besides the file type, since they can change at any moment, and the VFS might be using stale data without having first properly revalidated it.
