[PATCH 03/77] qemu-nbd: Close inherited stderr |
Date: |
Thu, 3 Sep 2020 15:58:21 -0500 |
From: Raphael Pour <raphael.pour@hetzner.com>
Close inherited stderr of the parent if fork_process is false.
Otherwise no one will close it. (introduced by e6df58a5)
This only affected 'qemu-nbd -c /dev/nbd0'.
