From a00ba0f49921fb19ac1fb77b50d0ed74e04ac062 Mon Sep 17 00:00:00 2001 From: Christian Hesse Date: Fri, 29 Jun 2018 11:16:19 +0200 Subject: Remove cow file early for non-persistent systems The kernel has an open file handle after setting up the mapping. We can remove it early to make sure it is gone on shutdown. This helps to keep the cow_device clean for non-persistent systems where cow_directory contains a version specific string.
