Mimi, Roberto,

If I recall correctly, we've discussed the process measurement issue
before, and I thought it was being resolved.  What is the current
status on a fix?

I don't recall discussing the ima_file_free() issue, but it looks like
the syzbot reports go back to 2024; is there a fix under development
for that?

Thanks.
