From 7cffbcd68f1c1579173e6d4d6fdfd5c99a4f5ba5 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Tue, 24 Jan 2023 11:29:58 -0800 Subject: exit: Expose "oops_count" to sysfs commit 9db89b41117024f80b38b15954017fb293133364 upstream. Since Oops count is now tracked and is a fairly interesting signal, add the entry /sys/kernel/oops_count to expose it to userspace. Cc: "Eric W.
