Official support for linux kernel 5.15

[lvd2]

How will this feature improve OpenZFS?

5.14 kernel is EOL now and 5.15 is going to be next LTS.

Currently 5.15 works fine with 2.0.6 and 2.1.1 as far as anyone's found; I believe the only reason it's not listed is that they both predate 5.15's actual release.

That said, whenever 2.1.2 and 2.0.7 drop, I would expect the supported range to include it.

Usually the META file is updated to indicate this though, I don't see it updated in any branch: https://github.com/openzfs/zfs/blob/master/META

If you look at the timing of the commits versus releases, those seem to have always happened a couple days before a new release of 2.0.x or 2.1.x that included support for it, so I would guess that such a commit will turn up around when the open PRs for 2.0.7/2.1.2 get merged into their respective branches in order to include it in them.

Arguably, I'm not sure that official support for kernels above 5.12 should technically have ever been claimed in 2.0.6/2.1.0/2.1.1 due to #12301. 😬 (Perhaps my fault, for not bringing up the supported kernel range thing at the time.)

Fortunately, #12759 got merged to master today and I suspect will make its way into 2.0.7 and 2.1.2 as well.

what is the usual openzfs release cadence? it's really unfortunate that filesystem is blocking kernel update.

Now that there's official 2.1.2 release with the support of 5.15 linux kernel, this issue is fixed
