[PATCH v3 mptcp-net 0/3] mptcp: cg and backlog follow-up

[Paolo Abeni <pabeni@redhat.com>]

This is a v2 of:

https://lore.kernel.org/mptcp/ed5c5ea1de503f6dc8a514b5eb4c9d16c431646f.1762696333.git.pabeni@redhat.com/

It turns out the previous revision was prone to a lot of ugly race.
Addressing them needs a some pre-reqs.

Races are due to MPJ subflows racing with accept() and possibly adding
non accounted memory to the backlog while the account code is trying to
handle backlog_len.

Paolo Abeni (3):
  mptcp: fix grafting corner case
  Squash-to: "mptcp: fix memcg accounting for passive sockets"
  Squash-to: "mptcp: leverage the backlog for RX packet processing"
