Subject: [PATCH proxmox-backup 2/9] datastore: limit scope of mutable reference in FixedIndexWriter::close
Date: Fri, 31 Jul 2026 16:21:15 +0200	[thread overview]
Message-ID: <20260731142430.289893-3-r.obkircher@proxmox.com> (raw)
In-Reply-To: <20260731142430.289893-1-r.obkircher@proxmox.com>

Eliminate the variable to make it clearer that the reference won't be
accessed after the memory is unmapped.
