Hi Alexei,
Based on Plumber's note [1], it sounds that the use case is tied to the BPF tracing where a call tp find_vma() call will be made on a process's context to fetch user space's symbols.
Am I right ? Is the find_vma() call made in the context of the process owning the mm struct ?
Thanks, Laurent.
