![]() To support redundant package schedulers more easily, this patch refactors __mptcp_push_pending() logic from: For each dfrag: While sends succeed: Call the scheduler (selects subflow and msk->snd_burst) Update subflow locks (push/release/acquire as needed) Send the dfrag data with mptcp_sendmsg_frag() Update already_sent, snd_nxt, snd_burst Update msk->first_pending Push/release on final subflow -> While first_pending isn't empty: Call the scheduler (selects subflow and msk->snd_burst) Update subflow locks (push/release/acquire as needed) For each pending dfrag: While sends succeed: Send the dfrag data with mptcp_sendmsg_frag() Update already_sent, snd_nxt, snd_burst Update msk->first_pending Break if required by msk->snd_burst / etc Push/release on final subflow Refactors __mptcp_subflow_push_pending logic from: For each dfrag: While sends succeed: Call the scheduler (selects subflow and msk->snd_burst) Send the dfrag data with mptcp_subflow_delegate(), break Send the dfrag data with mptcp_sendmsg_frag() Update dfrag->already_sent, msk->snd_nxt, msk->snd_burst Update msk->first_pending -> While first_pending isn't empty: Call the scheduler (selects subflow and msk->snd_burst) Send the dfrag data with mptcp_subflow_delegate(), break Send the dfrag data with mptcp_sendmsg_frag() For each pending dfrag: While sends succeed: Send the dfrag data with mptcp_sendmsg_frag() Update already_sent, snd_nxt, snd_burst Update msk->first_pending Break if required by msk->snd_burst / etc Move the duplicate code from __mptcp_push_pending() and __mptcp_subflow_push_pending() into a new helper function, named __subflow_push_pending(). Simplify __mptcp_push_pending() and __mptcp_subflow_push_pending() by invoking this helper. Also move the burst check conditions out of the function mptcp_subflow_get_send(), check them in __subflow_push_pending() in the inner "for each pending dfrag" loop.
