: getfh() certainly doesn't lock the leaf. After all, what should unlock it?
Maybe I misunderstand what:
NDINIT(&nd, LOOKUP, FOLLOW | LOCKLEAF, UIO_USERSPACE,
SCARG(uap, fname), p);
in the getfh code does.
: So there didn't exist any possibility to unlock the leaf after the call
: to getfh(). And locking it wouldn't have made any sense in the first
: place (NFS is stateless!).
I know it doesn't make sense, I was just looking at the code and
noticed that most of the other NDINIT calls didn't have LOCKLEAF in
