From 877a0893e3751022d2e60bea54dd5ac2e4026997 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Thu, 8 Dec 2011 15:25:56 -0800 Subject: [PATCH] Staging: lttng: remove from the drivers/staging/ tree The "proper" way to do this is to work with the existing in-kernel tracing subsystem and work to get the missing features that are in lttng into those subsystems.
