In this\ntime, userspace could queue up this same buffer before start_encode removes\nthe index from the ready queue. This would then lead to a case where the\nbuffer in the ready queue could be a self loop due to the\nWRITE_ONCE(prev->next, new) call in __list_add.\n\nWhen __list_del is finally called, the loop is already made so nothing\npoints back to ready queue list head and pointers are poisoned.\n\nA buffer should not be marked as DONE before the buffer is removed from\nm2m ready queue.
