-From: Mathieu Desnoyers <mathieu.desnoyers@polymtl.ca>
-Subject: LTTng instrumentation - ipv4
-
-Original patch header:
-  LTTng instrumentation - ipv4
-  
-  Keep track of interface up/down for ipv4. Allows to keep track of interface
-  address changes in a trace.
-  
-  Those tracepoints are used by LTTng.
-  
-  About the performance impact of tracepoints (which is comparable to markers),
-  even without immediate values optimizations, tests done by Hideo Aoki on ia64
-  show no regression. His test case was using hackbench on a kernel where
-  scheduler instrumentation (about 5 events in code scheduler code) was added.
-  See the "Tracepoints" patch header for performance result detail.
