Maybe he thinks of Linux Foundation Platinum Members ;)

XFS is actually really good, but Linux definitely need's a check-summing COW Filesystem that's usable.

FWIW, we do have CoW on XFS, but yeah no data-checksumming other than BTRFS. Hopefully bcachefs will be the go-to option someday.

Yes true and check-summing for metadata too, but not for the data. I have bigger hopes for XFS then bcachefs (maturity and really great dev's) but hopefully not that Stratis-thing from redhat....that sound's like a terrible idea.

Writeback latency spikes and lack of data checksums is the main issue with ext4 and xfs.

Btrfs has the checksums, but is a toy.

To my knowledge, NILFS2 (by NTT) is still the best filesystem Linux has in mainline. And, ironically, practically nobody does use it.

Does NILFS2 ensure data integrity? [0] claims that it doesn't actually check data checksums, but that's from 2011...

Yes it does:
