Return-Path: Date: Mon, 12 Jun 2017 22:06:22 +0000 (UTC) From: Mathieu Desnoyers Message-ID: <800720578.11295.1497305182681.JavaMail.zimbra@efficios.com> MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit Subject: [diamon-discuss] [RELEASE] LTTng modules 2.10.0-rc2, 2.9.3, 2.8.6 List-Id: DiaMon diagnostic and monitoring workgroup general discussions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , To: lttng-dev@lists.lttng.org, diamon-discuss@lists.linuxfoundation.org, linux-kernel The LTTng modules provide Linux kernel tracing capability to the LTTng tracer toolset. Those versions are bugfixes in the currently maintained stable branches of lttng-modules. They mainly contain: - Fix for the "PID tracker" feature, which should track pgid, which corresponds to the notion of process ID in user-space. It is now in sync with the feature in the UST tracing domain (application tracing), - Adding a "flush empty" ioctl for snapshots fixes cases where the Babeltrace lttng-live reader has issues keeping up with a steady stream of useless empty packets. This "flush empty" ioctl is introduced in backwards and forwards compatible ways, to ensure smooth upgrade within the stable versions of lttng-tools and lttng-modules. Those releases also add support for 4.12 release candidate kernels. Enjoy!
