This iteration includes many optimizations using the msk
socket lock to reduce the number of mptcp_data_lock contentions.

It additionally cleans a bit the mptcp_lock_sock() macro definitions
and fix a few checkpatches issues.

Still using the backlog, as per ML discussion

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.
