Subject: [PATCH net-next v2 02/11] net: remove netif_set_real_num_rx_queues() helper for when SYSFS=n
Date: Mon, 24 Mar 2025 15:45:28 -0700	[thread overview]
Message-ID: <20250324224537.248800-3-kuba@kernel.org> (raw)
In-Reply-To: <20250324224537.248800-1-kuba@kernel.org>

Since commit a953be53ce40 ("net-sysfs: add support for device-specific
rx queue sysfs attributes"), so for at least a decade now it is safe
to call net_rx_queue_update_kobjects() when SYSFS=n. That function
does its own ifdef-inery and will return 0. Remove the unnecessary
stub for netif_set_real_num_rx_queues().
