Have we completely given up on fixing the upcall? > That would be my preferred solution too. The whole problem is that this upcall takes too damned long to time out. But...how can it be fixed? Due to the way that rpc_pipefs interface works, there's no way that I can see to make that fail immediately if no one is listening on the pipe. You could reduce the timeout I guess but that's sort of a half-assed solution. IMO, we're long past due for a new upcall that uses a different design altogether. Maybe something based on call_usermodehelper that doesn't require a running daemon? -- Jeff Layton <jlayton@xxxxxxxxxx> -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
