Fine with me.
I just did a few stats.
commits between 4.19-rc1 and 4.19-final:
Total commits: 2098
Total Cc: stable 334 Cc: stable 119 35% Cc: stable #kver 10 3% Cc: stable Revert 0 0% Cc: stable Fixes 123 37% Cc: stable Fixes #kver 81 24%
Total Fixes only 584 Fixes only > 4.18 227 39% Fixes only <= 4.18 357 61%
and between 4.19 and todays top of tree:
Total commits: 12947
Total Cc: stable 251 Cc: stable 85 34% Cc: stable #kver 28 11% Cc: stable reverts 2 1% Cc: stable Fixes 79 31% Cc: stable Fixes #kver 55 22%
Total Fixes only 835 Fixes only > 4.19 830 99% Fixes only <= 4.19 5 1%
Not much change in the 'cc stable' ratio for those without any information and for those with Fixes tag and #kver.
The cc stable + kver and the cc stable + Fixes differ, but their sum is roughly the same.
But the real interesting change is that between 4.19-rc1 and 4.19-final the number of Fixes only (no CC stable) commits which fix a commit in 4.18 or earlier is rather high, while the same category on post 4.19 is minimal.
I'll run a larger and more detailed scan to figure out whether there is a trend or this is just random.
Thanks,
