Subject: fault-injection: allow stacktrace filter for x86-64
Date: Wed, 17 Aug 2022 08:03:29 +0000
This patchset allow fault injection to run on x86_64 and makes stacktrace
filter work as expected. With this, we can test a device driver module
with fault injection more easily.
This patch (of 4):
FAULT_INJECTION_STACKTRACE_FILTER option was apparently disallowed on
x86_64 because of problems with the stack unwinder:
commit 6d690dcac92a84f98fd774862628ff871b713660
Author: Akinobu Mita <akinobu.mita@xxxxxxxxx>

fault injection: disable stacktrace filter for x86-64
However, there is no problems whatsoever with this today. Let's allow
it again.
