Subject: [Question PATCH 0/1] mm: crash in vmalloc_to_page - misuse or bug?
Date: Thu, 22 Feb 2018 16:13:23 +0200 [thread overview]
Message-ID: <20180222141324.5696-1-igor.stoppa@huawei.com> (raw)
While trying to change the code of find_vm_area, I got an automated
notification that my code was breaking the testing of i386, based on the
0-day testing automation from 01.org
I started investigating the issue and noticed that it seems to be
reproducible also on top of plain 4.16-rc2, without any of my patches.
I'm still not 100% sure that I'm doing something sane, but I thought it
might be good to share the finding.
The patch contains both a minimal change, to trigger the crash, and a
snippet of the log of the crash i get.
