Subject: [PATCH net 0/7] mptcp: Path manager fixes for 5.19

The MPTCP userspace path manager is new in 5.19, and these patches fix
some issues in that new code.

Patches 1-3 fix path manager locking issues.

Patches 4 and 5 allow userspace path managers to change priority of
established subflows using the existing MPTCP_PM_CMD_SET_FLAGS generic
netlink command. Includes corresponding self test update.

Patches 6 and 7 fix accounting of available endpoint IDs and the
MPTCP_MIB_RMSUBFLOW counter.

Geliang Tang (1):
  mptcp: update MIB_RMSUBFLOW in cmd_sf_destroy

Kishen Maloor (2):
  mptcp: netlink: issue MP_PRIO signals from userspace PMs
  selftests: mptcp: userspace PM support for MP_PRIO signals

Mat Martineau (2):
  mptcp: Avoid acquiring PM lock for subflow priority changes
  mptcp: Acquire the subflow socket lock before modifying MP_PRIO flags

Paolo Abeni (2):
  mptcp: fix locking in mptcp_nl_cmd_sf_destroy()
  mptcp: fix local endpoint accounting
