To avoid the confusion, my question and a note are absolutely offtopic.

Could you remind me why
struct pid *pids[PIDTYPE_MAX] = {};
is not right? I seem to knew it some time before, but can't recall...
And just for the record, a note for myself. I need to recheck, but it seems
that the comment above flush_sigqueue(&tsk->pending) in __exit_signal() is
obsolete, so with some minimal changes we can move more work outside of
tasklist.
