Just to confirm, you are interested in this -rcu commit, correct?

2402d0eae589 ("kcsan: Add option for verbose reporting")

This one and the following are directly on top of the KCSAN stack
that is in -tip and thus -next:

48b1fc1 kcsan: Add option to allow watcher interruptions
2402d0e kcsan: Add option for verbose reporting
44656d3 kcsan: Add current->state to implicitly atomic accesses
e7b3410 kcsan: Fix a typo in a comment
e7325b7 kcsan: Update Documentation/dev-tools/kcsan.rst
1443b8c kcsan: Update API documentation in kcsan-checks.h

These are on top of this -tip commit:

f5d2313bd3c5 ("kcsan, trace: Make KCSAN compatible with tracing")

You can pull them in via the kcsan-dev.2020.03.25a branch if you wish.
