Looks like you just built on top of a random commit from Linus's tree:

commit f6cef5f8c37f58a3bc95b3754c3ae98e086631ca
Merge: 906a93befec8 8f06fb458539
Author: Linus Torvalds <torvalds@...ux-foundation.org>
Date:   Sun Mar 17 16:59:33 2024 -0700

    Merge tag 'i3c/for-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/i3c/linux

Linus prefers basing off of real tags or previous pulls from us.

Can you rebase your changes on v6.8 and resend?

  $ git checkout v6.8
  $ git cherry-pick f6cef5f8c37f58a3bc95b3754c3ae98e086631ca..trace-tools-v6.9

Appears to work fine.

Thanks!
