Oh dear, fatal_signal_pending() doesn't consider cases with no more userspace
instructions due to SIG_DFL on TERM/INT etc, that seems misleading :-( I had
(naively) believed it internally checks the same set as TASK_KILLABLE.
Chuxin, Muchun, can you please make it work using TASK_KILLABLE in a similar
way to how schedule_timeout_killable and friends do it instead, so that other
signals will be caught?
