I have always used the chronological order but your argument about
reviewers being able to quickly see the delta makes sense - will switch
to having the latest changes on the top in the next version.
By the way, looking at the current https://lore.kernel.org/lkml/ at the
time I am writing this, while most of v3+ submissions are indeed
using the "latest on the top" order, some aren't:
https://lore.kernel.org/lkml/20210813145302.3933-1-kevin3.tang@gmail.com/T/
https://lore.kernel.org/lkml/20211015024658.1353987-1-xianting.tian@linux.alibaba.com/T/
https://lore.kernel.org/lkml/YW%2Fq70dLyF+YudyF@T590/T/ (this one uses a
hybrid approach - current version changes on the top, remaining changeset
in chronological order).
Thanks,
Maciej
