Re: [LSF/MM TOPIC] blk-trace update vs API stability

Hannes Reinecke [off-list ref] writes:

At LSF I'd like to discuss
- Do we consider blktrace (and any other tracepoint in eg SCSI) as a
stable API?

I don't have a strong opinion on this.

- How do we go about modifying blktrace?

Blktrace has a version number associated with trace events.  Bump the
version for non-backward-compatible changes.

- Is this even desired?

Yes.
