You've cut the RIP line out of that report, so I cannot see if it's also in
find_get_pages() or not.  I suspect that it is, but nice to see confirmation.

Ah, I missed the "(Continue reading)" button, which reveals "Full output
here": that shows more, and indeed, RIP is at find_get_pages+0x46.

Interesting, but I don't know what's going on here.
