Bug ID: 16844
Summary: Adapt to tracepoint API changes in 3.15
Product: systemtap
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: runtime
Assignee: systemtap at sourceware dot org
Reporter: jistone at redhat dot com
The basic register_trace_foo() interface is unchanged, but that inline now uses
the __tracepoint_##foo data symbol rather than a #foo string for the underlying
tracepoint_probe_register() call, and not many tracepoints actually declare
EXPORT_TRACEPOINT_SYMBOL[_GPL].
The new, apparently preferred, option is to use for_each_kernel_tracepoint() to
iterate the built-in tracepoints, and use the new tracepoint module notifier to
examine mod->tracepoints_ptrs[] for the rest. Clients are also responsible for
unregistering tracepoints in modules that are unloading.
