From dced341b2d4f06668efaab33f88de5d287c0f45b Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (Red Hat)" Date: Tue, 14 Jan 2014 10:19:46 -0500 Subject: tracing: Have trace buffer point back to trace_array The trace buffer has a descriptor pointer that goes back to the trace array. But it was never assigned. Luckily, nothing uses it (yet), but it will in the future. Although nothing currently uses this, if any of the new features get backported to older kernels, and because this is such a simple change, I'm marking it for stable too.
