Subject: Re: [PATCH] lockdep: Improve consistency between lockdep and
hardware hardirqs states
Hi Waiman,
kernel test robot noticed the following build errors:
[auto build test ERROR on tip/locking/core]
[also build test ERROR on linus/master v6.10-rc3 next-20240613]
[If your patch is applied to the wrong git tree, kindly drop us a note.
And when submitting patch, we suggest to use '--base' as documented in
https://git-scm.com/docs/git-format-patch#_base_tree_information]
