[20:02] Hi, would this be place to ask a question about why an upstream kernel patch is not included in the corresponding Ubuntu kernel? [20:22] yes, that'd be on-topic here [20:27] So the patch is this one, Jul 2021: https://lkml.org/lkml/2021/7/12/1687 [20:27] 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] Launchpad bug 1929591 in mdadm (Ubuntu) "MD RAID 6 Periodic Kernel Panic Stack Overflow Double-Fault" [Undecided, Confirmed] [20:29] *for my Ubuntu 5.13 kernel, sorry [20:32] https://kernel.dance/#ad3fc798800fb7ca04c1dfc439dba946818048d8 -- it looks like it did land in the 5.12 stable series, yeah [20:34] Thanks! Is is normal that there is no 5.12 tags in the list here? https://github.com/torvalds/linux/commit/ad3fc798800fb7ca04c1dfc439dba946818048d8 [20:34] Commit ad3fc79 in torvalds/linux "md: revert io stats accounting" [20:39] 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] Commit 27f9d64 in gregkh/linux "md: revert io stats accounting" [20:59] Ah, thanks [21:00] I'm not sure either ^^ But thanks for the help, this gives some pointers to continue looking
