Subject: [PATCH 07/11] Kernel: Trigger BUG if data corruption is detected
Date: Sat, 19 Mar 2022 21:10:11 +0000 [thread overview]
Message-ID: <0588411b-01e1-cb02-0d2f-7e40831b3338@ipfire.org> (raw)
In-Reply-To: <771528ff-9bb0-2073-4819-471ab16bb920@ipfire.org>
[-- Attachment #1: Type: text/plain, Size: 3081 bytes --]
Since we cannot trust the kernel to do the right thing (tm) in such a
situation anymore, triggering a BUG is less bad than running on a kernel
in an undefined state.
