Internally, we use the merge strategy to combine as many branches as we can to run build testing, and bisect the issues if found.

Thanks, so far, we recommend to use --base option in our report mail, like [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] And we do need a place to put such information, so people can refer to. Without a public available site for us, we will update https://github.com/intel/lkp-tests/wiki firstly to host enough information. > > And the long-standing feature request we have: a simple web page > somewhere which says how far is it with testing.
