| Alsyia | Hi, would this be place to ask a question about why an upstream kernel patch is not included in the corresponding Ubuntu kernel? | 20:02 |
|---|---|---|
| sarnold | yes, that'd be on-topic here | 20:22 |
| Alsyia | So the patch is this one, Jul 2021: https://lkml.org/lkml/2021/7/12/1687 | 20:27 |
| Alsyia | My understanding is that it was included in upstream kernel 5.12 (but I'm starting to think I'm wrong about that? I'm not familiar with kernel dev conventions!) but I checked the source for my 5.13 kernel and it's not included in it. The related bug I'm interested about is this one: https://bugs.launchpad.net/ubuntu/+source/mdadm/+bug/1929591 | 20:27 |

| Alsyia | *for my Ubuntu 5.13 kernel, sorry | 20:29 |
| sarnold | https://kernel.dance/#ad3fc798800fb7ca04c1dfc439dba946818048d8 -- it looks like it did land in the 5.12 stable series, yeah | 20:32 |
| Alsyia | Thanks! Is is normal that there is no 5.12 tags in the list here? https://github.com/torvalds/linux/commit/ad3fc798800fb7ca04c1dfc439dba946818048d8 | 20:34 |
| ubottu | Commit ad3fc79 in torvalds/linux "md: revert io stats accounting" | 20:34 |
| sarnold | I'm not entirely sure how all that works.. you can see the backport on eg https://github.com/gregkh/linux/commit/27f9d646b165cb0f1d64989b19b50498dff93379 | 20:39 |
| ubottu | Commit 27f9d64 in gregkh/linux "md: revert io stats accounting" | 20:39 |
| Alsyia | Ah, thanks | 20:59 |
| Alsyia | I'm not sure either ^^ But thanks for the help, this gives some pointers to continue looking | 21:00 |
