[MPTCP] [PATCH v4 0/7] mptcp: just another complete datapath refactor

[Paolo Abeni]

[-- Attachment #1: Type: text/plain, Size: 909 bytes --]

This iteration drops completely backlog usage, as per Mat suggestions.

The only updated patch WRT the previous iteration is the last one:
 7/7 mptcp: use mptcp backlog.

Only lighlty tested, but at least it does not explode badly on the first
self-test iteration :)

Paolo Abeni (7):
  mptcp: open code mptcp variant for lock_sock
  mptcp: implement wmem reservation.
  mptcp: protect the rx path with the msk socket spinlock
  mptcp: allocate TX skbs in msk context.
  mptcp: avoid a few atomic ops in the rx path
  mptcp: simplify mptcp_nospace
  mptcp: use mptcp backlog.
