Here's another batch of MPTCP fixes for v5.13.

Patch 1 cleans up memory accounting between the MPTCP-level socket and
the subflows to more reliably transfer forward allocated memory under
pressure.

Patch 2 wakes up socket readers more reliably.

Patch 3 changes a WARN_ONCE to a pr_debug.

Patch 4 changes the selftests to only use syncookies in test cases where
they do not cause spurious failures.

Patch 5 modifies socket error reporting to avoid a possible soft lockup.


Paolo Abeni (5):
  mptcp: try harder to borrow memory from subflow under pressure
  mptcp: wake-up readers only for in sequence data
  mptcp: do not warn on bad input from the network
  selftests: mptcp: enable syncookie only in absence of reorders
  mptcp: fix soft lookup in subflow_error_report()
