Hmm.. your <linux/cred.h> file exposes "struct ucred" to user space (or at least has a #ifdef __KERNEL__ that does not protect it). Why? Also, I don't see how this is going to solve the credential clone problem, which basically says that sometimes you do _not_ want to do COW on the credentials (when changing them when they are shared with other threads) and sometimes you do (when changing them when they are shared with a background filesystem lookup). Any ideas on that? (And I _really_ don't like those trivial inline functions in [1/3] - I think it's much better to just show that we're doing a pointer dereference than trying to hide it behind some silly "current_fsuid()" inline function).
