Subject: [PATCH v2] blktrace: cleanup/fix registration locking
Date: Sun,  5 Nov 2017 09:21:46 -0700
Message-Id: <1509898908-7175-1-git-send-email-axboe@kernel.dk>
List-ID: <linux-block@vger.kernel.org>

One patch that fixes up a discrepancy in how we lock the queue for
blktrace registration, and one that fixes up how we globally
serialize registering the tracepoints.
