Don't have this issue. That mmput() is not tied to zapping mappings,
rather zapping files. IOW, I think you're saying exit_mmap() wasn't
running due to your get_task_mm() (quite understandable, you still hold
a ref), whereas this ref is tied to exit_files().
So do_exit would do:
exit_mm
mmput <-- not dropped yet
exit_files
->release
mmput <-- dropped here
