The patch titled
Subject: kasan: respect /proc/sys/kernel/traceoff_on_warning
has been removed from the -mm tree. Its filename was
kasan-respect-proc-sys-kernel-traceoff_on_warning.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Peter Zijlstra <peterz@infradead.org>
Subject: kasan: respect /proc/sys/kernel/traceoff_on_warning
After much waiting I finally reproduced a KASAN issue, only to find my
trace-buffer empty of useful information because it got spooled out :/
Make kasan_report honour the /proc/sys/kernel/traceoff_on_warning
interface.
