[PATCH mptcp-next 0/3] mptcp: avoid data-races around the sysctls

From: Gang Yan <[email protected]>

Hi,

As decribed in [1], this series is for addressing the KCSAN issues in
sysctls.

Following the tcp_congestion_control() model, patch 1 and 2 now store
pointers to the immutable ops and swap them atomically via xchg().

Patch 3 (from Matthieu) covers the remaining scalar sysctls with READ_ONCE().

Gang Yan (2):
  mptcp: sched: change scheduler sysctl atomically
  mptcp: pm: change path_manager sysctl atomically

Matthieu Baerts (NGI0) (1):
  mptcp: use READ_ONCE() over sysctls
