Subject: [pbs-devel] [PATCH proxmox-backup v2 1/3] chunk store: limit scope for atime update helper methods
Date: Thu, 6 Nov 2025 18:13:56 +0100 [thread overview]
Message-ID: <20251106171358.865503-2-c.ebner@proxmox.com> (raw)
In-Reply-To: <20251106171358.865503-1-c.ebner@proxmox.com>
In preparation for fixing a race window due to missing chunk store
locking. These should never be called from outside the crate.
