Subject: [PATCH net-next v2 8/9] net: core: export skb_defer_free_flush
Date: Tue, 25 Nov 2025 13:00:35 -0700 [thread overview]
Message-ID: <20251125200041.1565663-9-jon@nutanix.com> (raw)
In-Reply-To: <20251125200041.1565663-1-jon@nutanix.com>
Export skb_defer_free_flush so that it can be invoked in other modules,
which is helpful in situations where processing the deferred backlog
at specific cache refill points may be preferred.
