Subject: [PATCH v4 09/14] tools/lib/lockdep: New stacktrace API
Date: Tue, 4 Aug 2020 20:10:38 -0400 [thread overview]
Message-ID: <20200805001043.3331907-10-sashal@kernel.org> (raw)
In-Reply-To: <20200805001043.3331907-1-sashal@kernel.org>
The kernel switched to using kernel/stacktrace.c, and the API slightly
changed.
Adjust it to make stack traces work again.
