Looks like you just built on top of a random commit from Linus's tree:
commit f6cef5f8c37f58a3bc95b3754c3ae98e086631ca
Merge: 906a93befec8 8f06fb458539
Author: Linus Torvalds <torva...@linux-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!
