-From: Mathieu Desnoyers <mathieu.desnoyers@polymtl.ca>
-Subject: LTTng instrumentation - page_alloc
-
-Original patch header:
-  LTTng instrumentation - page_alloc
-  
-  Paging activity instrumentation. Instruments page allocation/free to keep track
-  of page allocation. This does not cover hugetlb activity, which is covered by a
-  separate patch.
-  
-  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.
