-From b6e0ad2af132a9ddd859735408da381e20a31c72 Mon Sep 17 00:00:00 2001
-From: Omar Sandoval <osandov@osandov.com>

-Subject: [PATCH] tests: check for missing or invalid /proc/kcore for Linux
- kernel tests
-
-If /proc/kcore is missing (e.g., because CONFIG_PROC_KCORE is not
-enabled) or invalid (e.g., Docker mounts /dev/null over /proc/kcore),
-then skip the tests.
