Subject: kasan: respect /proc/sys/kernel/traceoff_on_warning

From: Peter Zijlstra <[email protected]>

[ Upstream commit 4f40c6e5627ea73b4e7c615c59631f38cc880885 ]

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.
