From 292e6077b04091d138bae6010fb9fdc958170d64 Mon Sep 17 00:00:00 2001 From: Paolo Abeni Date: Tue, 26 Oct 2021 16:29:14 -0700 Subject: net: introduce sk_forward_alloc_get() A later patch will change the MPTCP memory accounting schema in such a way that MPTCP sockets will encode the total amount of forward allocated memory in two separate fields (one for tx and one for rx). MPTCP sockets will use their own helper to provide the accurate amount of fwd allocated memory. To allow the above, this patch adds a new, optional, sk method to fetch the fwd memory, wrap the call in a new helper and use it where it is appropriate.
