[PATCH] lockdep: annotate sunrpc code
Add i_mutex ordering annotations to the sunrpc rpc_pipe code. This code has 3
levels of i_mutex hierarchy in some cases: parent dir, client dir and file
inside client dir; the i_mutex ordering is I_MUTEX_PARENT -> I_MUTEX_CHILD ->
I_MUTEX_NORMAL
This patch applies this ordering annotation to the various functions. This is
in line with the VFS expected ordering where it is always OK to lock a child
after locking a parent; the sunrpc code is very diligent in doing this
correctly.
Has no effect on non-lockdep kernels.
