From 2b481ba59a471a9488eb63d10435b700e2968f9f Mon Sep 17 00:00:00 2001 From: Olivier Matz Date: Wed, 13 Jul 2022 16:34:57 +0200 Subject: [PATCH] doc: announce behavior change for device NUMA node field The dev->device.numa_node field is set by the bus driver for each device it manages to indicate on which NUMA node this device lies. When this information is unknown, the assigned value is not consistent accross the bus drivers. In v22.11, the value will be set to -1 in this case.
