Subject: [PATCH 09/14] net/sfc: rework locking in proxy code
Date: Fri, 24 Feb 2023 09:16:37 +0100 [thread overview]
Message-ID: <20230224081642.2566619-10-david.marchand@redhat.com> (raw)
In-Reply-To: <20230224081642.2566619-1-david.marchand@redhat.com>
Remove one extra layer for proxy code: sfc_get_adapter_by_pf_port_id()
now only resolves the sa object and sfc_adapter_(|un)lock() are added
were necessary.
This will simplify lock checks later.
