[PATCH v2 0/5] Various fixes around undefined behavior

[Ian Rogers]

Fix various undefined behavior issues, improve tests to make them
easier to diagnose and add assertions so that problems don't recur.

v2: Add Namhyung's acked-by. Drop container_of assert that ptr !=
    NULL, to simplify the series. The bsearch UB fix was picked up as
    a patch by CT:

    It seems this patch series fell-through the cracks as v1 was
    sent/acked 9 months ago.

v1: https://lore.kernel.org/lkml/20241213210425.526512-1-irogers@xxxxxxxxxx/
