Subject: [pbs-devel] [PATCH v4 pxar 03/58] decoder: factor out skip part from skip_entry
Date: Mon, 29 Apr 2024 14:10:07 +0200 [thread overview]
Message-ID: <20240429121102.315059-4-c.ebner@proxmox.com> (raw)
In-Reply-To: <20240429121102.315059-1-c.ebner@proxmox.com>
Make the skip part reusable for a different input.
In preparation for skipping payload paddings in a separated input.
