Subject: [for-next][PATCH 0/2] tracing: Snapshot command line and branch tracer fix


Two more patches to my queue. I added alloc_snapshot to the kernel
command line parameter to alloc allocation of the snapshot buffer
when the main tracing buffer is allocated, allowing the use of
tracing_snapshot() without the fear of it not being allocated.

Also Fengguang Wu's tests discovered that my changes broke the branch
tracer. I guess I should add that to my test suite ;-)

Steven Rostedt (Red Hat) (2):
      tracing: Add alloc_snapshot kernel command line parameter
      tracing: Fix the branch tracer that broke with buffer change
