Subject: Re: [PATCH 1/4 net-next] tcp: consolidate PRR packet accounting

> This patch series fix an undo bug in fast recovery: the sender

> The first patch prepares the fix by consolidating the accounting

> newly_acked_sacked everytime sacked_out is adjusted.  Also pass
> acked and prior_unsacked as const type because they are readonly
