Subject: [PATCH v4 2/2] PCI: AtomicOps: Update references to PCIe spec
Date: Fri, 13 Mar 2026 17:49:35 +0100 [thread overview]
Message-ID: <20260313-fix_pciatops-v4-2-93bc70a63935@linux.ibm.com> (raw)
In-Reply-To: <20260313-fix_pciatops-v4-0-93bc70a63935@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.
