This changelog is completely made up. Which failure is ignored there and
whats the inconsistent state of a previous attempt?

The -EBUSY comment is a leftover from the original implementation. and
the pr_warn() about the vdso clock mode is harmless as it still leaves
the system in a consistent state. Just the VDSO functionality is not
enabled.

This AI slop starts to become annoying.
