Subject: BUG: sleeping function called from invalid context at include/linux/freezer.h:45

Dear all

with the latest kernel. I got the below bug message.
It calls the sleep function. Does it intended operation?

static inline bool try_to_freeze(void)
{
        might_sleep();
        if (likely(!freezing(current)))
                return false;
        return __refrigerator(false);
}
