From 05b8d59015f8a5ce26c8bbaa8053b5bc7cb1a77b Mon Sep 17 00:00:00 2001 From: Phil Estes Date: Wed, 13 Dec 2017 23:38:22 -0500 Subject: [PATCH] Fix overlay2 storage driver inside a user namespace The overlay2 driver was not setting up the archive.TarOptions field properly like other storage backend routes to "applyTarLayer" functionality. The InUserNS field is populated now for overlay2 using the same query function used by the other storage drivers.
