SubjectRe: schedule_timeout() called with state TASK_RUNNING from fs/select.c

No.

Yes, it is pointless to call schedule() if it is known that ->state ==
TASK_RUNNING, but sometimes the task doesn't know its state when it
calls schedule/schedule_timeout, the state could be changed by
try_to_wake_up().

See wait_event_timeout() as an example.
