[PATCH v2 mptcp-net 0/5] mptcp: a bunch of data race fixes

[Paolo Abeni <pabeni@redhat.com>]

The patch 1 && 4 are direct response to recently reported KCSAN
splat.

The patch 2 && 3 are just by code inspection of related code path.
Patch 3/5 is there mostly to make the next one simple, even if the race
mentioned in such patch should be real (but very tiny, if possible at
all).

This iteration addresses a compile warning in patch 2/5 reported by
kbuild bot.

Patch 5/5 is new in this round, fixes an unrelated issue found by code
inspection. I should have posted separatelly

Paolo Abeni (5):
  mptcp: add annotations around msk->subflow accesses
  mptcp: consolidate passive msk socket initialization
  mptcp: fix data race around msk->first access
  mptcp: add annotations around sk->sk_shutdown accesses
  mptcp: fix active subflow finalization.
