From 18cdbb3c80b05e4251082d4bc45d90515afb2328 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 11 Oct 2017 13:46:17 +0200 Subject: [PATCH] tests: Add a script to aid bisecting Linux kernel with hwsim VM I find myself writing a version of this script every now and then, but there's little point in that - just add one to the tree so we can use it again.
