These patches provide a kernel tracing interface called "trace".
The motivation for "trace" is to: - Provide a simple set of tracing primitives that will utilize the high- performance and low-overhead of relayfs for passing traces data from kernel to user space. - Provide a common user interface for managing kernel traces. - Allow for binary as well as ascii trace data. - Incorporate features from the systemtap runtime that are useful to others. History- Versions of this code have been submitted for review under a couple of different names. The original submission was called UTT, it was later re-submitted as GTSC. Christoph Hellwig commented "The code looks fine ...but the name is just dumb". Following Christoph's advice, I changed the name to simply "Trace". This patch addresses review comments made by Christoph Hellwig and Mathieu Desnoyers. Changes include the addition of a mutex and synchronization protecting trace state changes (using RCU) and the reduction of the number of exports.
