Cover letter [patch 0/9] LTTng core kernel instrumentation

Hi,

This is the core of the Linux kernel LTTng instrumentation. I left out what I considered that would be eventually covered by a wide syscall instrumentation and I also picked the most important pieces of instrumentation. The LTTng tree contains more tracepoints, some of which (e.g. mm instrumentation) will be proposed later once we agree on the tracepoints proposed in this patchset.

Ingo, the irq and softirq instrumentation patches will probably clash with the patches from Jason you currently have in your tree. Please see the individual changelogs for details.

This patchset applies over 2.6.29 in the following order :

irq-handle-prepare-for-instrumentation.patch lttng-instrumentation-irq.patch lttng-instrumentation-tasklets.patch lttng-instrumentation-softirq.patch lttng-instrumentation-scheduler-fixup-task-migration.patch lttng-instrumentation-timer.patch lttng-instrumentation-kernel.patch lttng-instrumentation-filemap.patch lttng-instrumentation-swap.patch

Thanks,

Mathieu
