Great! Just what we needed. > > If you post things that need to be applied on top of that branch, > please mention that in the cover letter. Ok. I'll mention that in the cover letters of my patchsets. I've already got several R-b/T-b tags in the series: https://lore.kernel.org/linux-pci/20220610082535.12802-1-Sergey.Semin@xxxxxxxxxxxxxxxxxxxx/ Could you also have a look at it? If no objection we can either merge it in right away into the pci/edma branch or wait for a little while for a few more rc-cycles until I get to fix all the comments posted for the dependant patchsets. > > I don't guarantee the immutability of the branch because sometimes I > fix typos or similar errors before the merge window.
