From 01074e5b34719537cef474c6b81d4f55e6427639 Mon Sep 17 00:00:00 2001 From: Bogdan Purcareata Date: Fri, 8 Jan 2016 15:38:35 +0000 Subject: [PATCH] open_without_symlink: Account when prefix is empty string In the current implementation, the open_without_symlink function will default to opening the root mount only if the passed rootfs prefix is null. It doesn't account for the case where this prefix is passed as an empty string. Properly handle this second case as well.
