3.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Trond Myklebust <Trond.Myklebust@xxxxxxxxxx> commit 00326ed6442c66021cd4b5e19e80f3e2027d5d42 upstream. There is no need for the kernel to time out the AF_LOCAL connection to the rpcbind socket, and doing so is problematic because when it is time to reconnect, our process may no longer be using the same mount namespace.
