Please use lore.kernel.org that doesn't corrupt whitespace in patches
or lose header information:

https://lore.kernel.org/lkml/20240113213347.9562-1-pchelkin@xxxxxxxxx/

although that seems to be a strange definition of "in flight". It was
sent out 8 days ago, and apparently nobody thought to include it in
the drm fixes pile that came in last Friday.

So it made it into rc1, even though it was reported a week before.

It also looks like some mailing list there is mangling emails - if you
use 'all' instead of 'lkml', lore reports multiple emails with the
same message-id, and it all looks messier as a result.

I assume it's dri-devel@xxxxxxxxxxxxxxxxxxxxx that messes up, mainly
because I don't tend to see this behaviour when only the usual
kernel.org mailing lists are involved.
