[lttng-dev] [RELEASE] LTTng modules 2.6.0 (Gaia)

[Mathieu Desnoyers]

We are now releasing the 2.6.0 LTTng modules Linux kernel tracer.

New & Noteworthy features in the LTTng Linux kernel tracer 2.6.0: 

- System call filtering! Fine-tune which system calls you want
  to trace or not,
- We now gather in/out parameters of system calls at entry and
  exit of the syscall. Please note that the system call event
  semantic (naming) have changed in this release. You may have
  to update your analysis if they depended on the old semantic,
- Trace NMI handlers, using the new NMI-safe clock monotonic
  available in kernels >= 3.17.
