Subject: Re: [Devel] [PATCH hci-8.1 3/8] ms/mptcp: move the stale logic out of retrans scheduler
Date: Fri, 6 Nov 2026 03:07:40 +0000 [thread overview]
Message-ID: <010701a1aed3849d-839292ea-3f49-4279-8451-5545ad0d8c7f-000000@eu-central-1.amazonses.com> (raw)
In-Reply-To: <20261106030306.16014-4-eva.kurchatova@virtuozzo.com>
> From: Paolo Abeni <pabeni@redhat.com>
>
> This allow separating the stale logic invocation and the retrans
> scheduler, and will simplify the next patch.
>
> It's also a cleaner design as the retrans scheduler has currently
> too many side effects. As a possible downside, the retrans work will
> now traverse the subflows list additional times; that does not matter
> much, as this is slowpath.
>
> While at it, pick more accurate names for the involved helpers and
> explicitly note that the per subflow stale data is under msk socket
> lock protection.
>
> The scheduler and the stale logic may observe different subflow
> [ ... ]
> "stale" bit leaves the bitfield, and __unused grows from 9 to 10.

> https://virtuozzo.atlassian.net/browse/VSTOR-153491
> Feature: fix ms/net
