[PATCH v1 2/5] perf test: Make sure maps to have a machine
From: Namhyung Kim
Date: Sun Oct 18 2026 - 12:39:55 EST
It's be easier if we could guarantee that maps always have a machine.
IIUC this is true for all real use cases, but only the test code has
an exception. Let's get rid of it and make sure they have machines.
