From 3913c78c3ab61500ddf7c2c9617cc4f8e2c583e0 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Sun, 8 Feb 2015 21:44:04 -0500 Subject: SUNRPC: Handle EADDRINUSE on connect Now that we're setting SO_REUSEPORT, we still need to handle the case where a connect() is attempted, but the old socket is still lingering. Essentially, all we want to do here is handle the error by waiting a few seconds and then retrying.
