Subject: Re: [Devel] [PATCH hci-8.1 v6 06/12] dm-ploop: factor out ploop_read_delta() from ploop_add_delta()
Date: Tue, 13 Oct 2026 11:25:33 +0000 [thread overview]
Message-ID: <010701a13502b7bf-0a38c390-a228-4ea9-b30f-9121e0205039-000000@eu-central-1.amazonses.com> (raw)
In-Reply-To: <20261013111604.142989-7-alexander.ivanov@virtuozzo.com>
> Move reading of delta BAT and applying its mappings to
> ploop->bat_entries into a separate function ploop_read_delta(). It
> will be used to reload metadata of already added deltas.
>
> ploop_read_delta() takes is_raw from deltas[level], so ploop_add_delta()
> sets it before the call.
>
> Replace the stale comment of ploop_add_delta(): it claimed deltas are
> added from oldest to newest, while ploop_add_deltas_stack() adds them
> from top to base, which ploop_read_delta() relies on.
>
> No functional changes.
>
> https://virtuozzo.atlassian.net/browse/VSTOR-148171
> Feature: dm-ploop: ploop target driver
>
> Signed-off-by: Alexander Ivanov <alexander.ivanov@virtuozzo.com>
