The output is part of Android bugreports, it's not parsed
automatically but the information is very useful even to manually look
at. Since Treble, we have more processes using binder, and some 32-bit
Android targets run out of vmalloc space because every process using
binder allocates 1MB in vmalloc address space. 1MB is overkill for
many processes, and this helps us find out which processes that are.

Yes.
