It would be great if you can give more information in the commit message
about why the usage of next_thread() is wrong in bpf/task_iter.c.
IIUC, some information is presented in :
  https://lore.kernel.org/all/20230824143112.GA31208@xxxxxxxxxx/

Also, please add 'bpf' in the subject tag ([PATCH bpf 0/3]) to
make it clear the patch should be applied to bpf tree.
