From 24cf707ed71534f6c4dc9a4a04f9a7b4c93d286b Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Tue, 22 Mar 2022 18:20:07 +0100 Subject: [PATCH] efi_loader: initrddump: drain input before prompt Up to now the initrddump.efi application has drained the input after showing the prompt. This works for humans but leads to problems when automating testing. If the input is drained, this should be done before showing the prompt.
