Merge branch 'mptcp-fixes-and-tracepoints'
Mat Martineau says:
====================
mptcp: Fixes and tracepoints from the mptcp tree
Here's one more batch of changes that we've tested out in the MPTCP tree.
Patch 1 makes the MPTCP KUnit config symbol more consistent with other
subsystems.
Patch 2 fixes a couple of format specifiers in pr_debug()s
Patches 3-7 add four helpful tracepoints for MPTCP.
Patch 8 is a one-line refactor to use an available helper macro.
====================
