The quilt patch titled Subject: fault-injection: allow stacktrace filter for x86-64 has been removed from the -mm tree. Its filename was fault-injection-allow-stacktrace-filter-for-x86-64.patch This patch was dropped because it was merged into the mm-nonmm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Wei Yongjun <weiyongjun1@xxxxxxxxxx> 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> Date: Sat May 12 10:36:53 2007 -0700 fault injection: disable stacktrace filter for x86-64 However, there is no problems whatsoever with this today. Let's allow it again.
