From 505a0ef15f96c6c43ec719c9fc1833d98957bb39 Mon Sep 17 00:00:00 2001 From: Alexander Potapenko Date: Mon, 6 Apr 2020 20:10:22 -0700 Subject: kasan: stackdepot: move filter_irq_stacks() to stackdepot.c filter_irq_stacks() can be used by other tools (e.g. KMSAN), so it needs to be moved to a common location. lib/stackdepot.c seems a good place, as filter_irq_stacks() is usually applied to the output of stack_trace_save(). This patch has been previously mailed as part of KMSAN RFC patch series.
