Hi Peter, thanks for the feedback. What do you mean by "trace
notification" ? We seem to have a trace event in that function you
mentioned. Also, accounting for that function is enough to
differentiate when the compaction is triggered by the kernel itself or
by the user (which is our use case here) ?

Cheers,


Guilherme
