These patches provide a kernel tracing interface called "trace".
ChangeLog: -Updated to 2.6.25-rc2-mm1 -Removed sem_watch example, to hard to maintain. -Added a new example that demonstrates per-cpu continuous tracing of data generated using marker probes. -Removed inline from relay patch. -Moved examples into /sample directory.
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.
Patches are built against 2.6.25-rc2-mm1. Tested on: 2.6.25-rc3
Summary of patches: [patch 1/3] Relay Reset Consumed [patch 2/3] Trace code and documentation [patch 3/3] Trace sample
Note: Patch 1/3 provides a service used by patch 2/3 thus must be applied first or at the same time.
