One of the issues with Meltdown/Spectre in particular is that the |
| 8 |
affected parts of the kernel have undergone some change over the |
| 9 |
years, and the changes themselves are not trivial. For some of the |
| 10 |
much older kernels the fixes are basically complete rewrites, with |
| 11 |
their own quality issues and timelines. For 4.9 that probably isn't |
| 12 |
as much of a factor, but it wouldn't surprise me if the changes still |
| 13 |
migrate their way backwards in time. There have been regressions with |
| 14 |
some of these changes, and that being the case the maintainers might |
| 15 |
want to both reduce the number of people impacted and also test them |
| 16 |
first on the kernels most similar to mainline where the patches were |
| 17 |
developed. |
