Subject: [PATCH v2 10/12] tools/lib/lockdep: New stacktrace API
Date: Sat, 18 Apr 2020 21:57:52 -0400 [thread overview]
Message-ID: <20200419015754.24456-11-sashal@kernel.org> (raw)
In-Reply-To: <20200419015754.24456-1-sashal@kernel.org>
The kernel switched to using kernel/stacktrace.c, and the API slightly
changed.
Adjust it to make stack traces work again.
