From ef9bef2bfed36424a3a6678d76d9eb7b710de1ac Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Tue, 7 Jul 2020 20:51:34 +0200 Subject: env: Add H_DEFAULT flag Add another internal environment flag which indicates that the operation is resetting the environment to the default one. This allows the env code to discern between import of external environment and reset to default.
