[PATCH] kcov: do not instrument lib/stackdepot.c
From: Alexander Potapenko
Date: Fri Sep 23 2016 - 10:29:55 EST
There's no point in collecting coverage from lib/stackdepot.c, as it is
not a function of syscall inputs. Disabling kcov instrumentation for
that file will reduce the coverage noise level.
