This seems to vary on per-subsystem basis, for netdev where I contribute the vast majority of the time, putting the changelog in the cover letter works, but I will do it on a per-patch basis next time. > > Your patch [1/3] has a Fixes: tag but does not Cc stable@vger.kernel.org, so > you'll have to send a v3. > > I reviewed [2/3] and it looks good to me, but I'm a bit concerned about > Nikolaus' reported issue. > > Thomas, if you can wait a few days, I can test it on my CI20 and if it works > report back with a Tested-by: tag. Thanks Paul, yes please do test it because I could not reproduce what Nikolaus reported, that makes me think there must be additional configuration options and/or patches being carried that could be responsible. -- Florian
