From 44a8bdea19dff1abcdc4528e5f7e038b18ee5255 Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Tue, 10 Jul 2012 18:31:05 -0500 Subject: [PATCH] slob: Fix early boot kernel crash Commit fd3142a59af2012a7c5dc72ec97a4935ff1c5fc6 broke slob since a piece of a change for a later patch slipped into it. Fengguang Wu writes: The commit crashes the kernel w/o any dmesg output (the attached one is created by the script as a summary for that run). This is very reproducible in kvm for the attached config.
