linuxPackages: 6.1 -> 6.6

[mweinelt]

The latest longterm kernel release series is 6.6, and we should roll it out as the default now, to receive as much testing as possible before the NixOS 24.05 release.

I hope I'm holding this correctly. Also, happy to receive feedback on the commit message.

nix-repl> linuxPackages.kernel.version
"6.6.15"

We discussed this a bit starting from #284724 (comment). tl;dr, the next ZFS patch release will support these kernels. Normally I'd say we don't care about out-of-tree modules, but since it seems like this is imminent, I think on balance we might as well wait a week or two.

Maybe this bump should be mentioned in the 24.05 changelog.
This is what has been done in #215313

2.2.2 already supports the 6.6 release.

2.2.2 already supports the 6.6 release.

Not on aarch64 unless I'm mistaken, because it doesn't have openzfs/zfs#15711.

ZFS released

[vcunat]

Opened as #290768

[dcarosone]

Is this now unblocked? Anything else it's waiting on?

[vcunat]

Maybe #291547 but I don't expect it's blocking this. Feedback from more people could help I guess.

Personally I've been using 6.6 for some time now on my desktop, VM and a laptop for work, 2 personal laptops and an aarch64 VPS. Didn't notice any issues anywhere.
Also since today I'm running OpenZFS 2.2.3 on that VPS without removeLinuxDRM just fine.

I suspected we should've checked -small before merging. This broke nixosTests.nfs3.simple
https://hydra.nixos.org/build/251337696

[mweinelt]

Broke somewhere between 6.3.12 and 6.4.0. The real issue is that we don't test the latest kernels incrementally.

[alyssais]

If we want to fix the nfs3 test (I think we should, but I don't know anything about NFS), the first bad commit is https://git.kernel.org/linus/bfca7a6f0c75f5d97f5efc2c80cca55bdbf5f79a, which looks like a clue.
