Let's be clear about the facts, then.

You reported the bug.  Our team fixed it â?? the next day.  May 28, our
v1.  You confirmed on May 29 that our v3 fixes your reproducer.

Since then, you've posted three versions â?? v1, v2, v3 â?? that
incrementally copy the work we developed and refined through seven
iterations.  Your v2 copied our lock-move skeleton.  Your v3 copied the
irq_chain_mutex rename, __must_hold(), and lockdep_assert_held() â?? all
written by us, all reviewed by Jiri on our patches.

You list these as your own "Changes in v3" with zero attribution.

This is not a "patch ownership discussion."  You copied our code.  The
kernel is GPLv2 â?? that means you can use the code, but you must
preserve the copyright notices.  Co-developed-by is the mechanism for
that.

You reported the bug â?? we fixed it first.  We credited you.  Now add
the tags.
