I'm not seeing ea74cdedda8b9575d7e94198d38f12943ac41343, but was hoping to see it with 2.3.3 after https://github.com/openzfs/zfs/pull/17340 got merged.

It had been part of the last staging preparations in https://github.com/openzfs/zfs/pull/17371

I'm not seeing ea74cde, but was hoping to see it with 2.3.3 after #17340 got merged.

Both of the PRs fill openzfs:zfs-2.3.3-staging branch. I see the "Fix 2 bugs" commit already there.

How about https://github.com/openzfs/zfs/commit/b7f919d22845aee34710e1cafa0ca601f26df4a8 also?

Good idea. Added, along with the https://github.com/openzfs/zfs/commit/284580c8780e056f4f33b89f49eeeedeef9af26b dependency.

I also went ahead and pulled in the parallel ARC eviction optimizations.

We should also backport these gang block changes @robn mentioned in the first staging PR. It looks like that'll take a bit of work, so I haven't yet included them in this PR.

5f5321effa Handle interaction between gang blocks, copies, and FDT. 9250403ba6 Make ganging redundancy respect redundant_metadata property (#17073)

[amotin]

@behlendorf I suspect "Remove mg_allocators" depends on "Unified allocation throttling". We have them both in our TrueNAS patch set, but see yourself if that is too much for 2.3.

[robn]

I won't have time to even look at #17123 until midweek. @pcd1193182 any chance you could take a look? iirc the idea is the same, just the setup is a bit different without the "variable size gang header" change.

[behlendorf]

@amotin thanks, I dropped "Remove mg_allocators" from the patch stack. I'd love to add "ZIL: Relax parallel write ZIOs processing" but that feels a bit too fresh. I'll pick it up next time.

@robn I was able to pick up the TrueNAS backports of https://github.com/openzfs/zfs/pull/17123, but it would be great if either you or @pcd1193182 could review those changes.

Dropped the following commits, they need a bit more work.
