From 002f1d4aaefa9abdd50e3e8906ae828c31d038e6 Mon Sep 17 00:00:00 2001 From: Ian Gudger Date: Fri, 20 Sep 2019 14:08:46 -0700 Subject: Allow waiting for LinkEndpoint worker goroutines to finish. Previously, the only safe way to use an fdbased endpoint was to leak the FD. This change makes it possible to safely close the FD. This is the first step towards having stoppable stacks.
