Subject: [PATCH rdma-next 07/13] RDMA/srp: Make the SRP sysfs class net namespace aware
Date: Thu,  9 Jul 2026 11:55:26 +0200	[thread overview]
Message-ID: <20260709095532.855647-8-jiri@resnulli.us> (raw)
In-Reply-To: <20260709095532.855647-1-jiri@resnulli.us>

From: Jiri Pirko <jiri@nvidia.com>

Tag srp_class by the RDMA device's net namespace so SRP hosts derived from
same-named RDMA devices can coexist across namespaces.
