FYI, we noticed a +5291 bytes kernel size regression due to commit:
commit: cdd28ad2d8110099e43527e96d059c5639809680 (READ_ONCE: Use data_race() to avoid
KCSAN instrumentation)
https://git.kernel.org/pub/scm/linux/kernel/git/peterz/queue.git locking/kcsan
Details as below (size data is obtained by `nm --size-sort vmlinux`):
88f1be32: kcsan: Rework data_race() so that it can be used by READ_ONCE()
cdd28ad2: READ_ONCE: Use data_race() to avoid KCSAN instrumentation
