In "ovl: stack file ops" this:
AV: make it use open_with_fake_path(), don't mess with override_creds
Maybe it's the way to go, but looks broken as is; e.g. NFS does call
current_creds() from its open method to get the credentials to work
with.
Okay, so ->open() is a file op, and file ops should use file->f_cred,
but how are we going to enforce this?
Thanks,
