Subject: [PATCH v6 2/2] PCI: AtomicOps: Update references to PCIe spec
Date: Wed, 25 Mar 2026 16:16:18 +0100 [thread overview]
Message-ID: <20260325-fix_pciatops-v6-2-10bf19d76dd1@linux.ibm.com> (raw)
In-Reply-To: <20260325-fix_pciatops-v6-0-10bf19d76dd1@linux.ibm.com>
Point to the relevant sections in the most recent release 7.0 of the
PCIe spec. Text has mostly just moved around without any semantic
change.
