Several categories of fixes from the mptcp tree:
Patches 1-3 are fixes related to MP_FAIL and FASTCLOSE, to make sure
MIBs are accurate, and to handle MP_FAIL transmission and responses at
the correct times. sk_timer conflicts are also resolved.
Patches 4 and 6 handle two separate race conditions, one at socket
shutdown and one with unaccepted subflows.
Patch 5 makes sure read operations are not blocked during fallback to
TCP.
Patch 7 improves the diag selftest, which were incorrectly failing on
slow machines (like the VMs used for CI testing).
Patch 8 avoids possible symbol redefinition errors in the userspace
mptcp.h file.
Patch 9 fixes a selftest build issue with gcc 12.
