Dave is going to hate me for this, but.. I've been looking over some of the interfaces here, and I'm starting to very seriously questioning the design decisions of storing the fsverity hashes in xattrs. Yes, storing them beyond i_size in the file is a bit of a hack, but it allows to reuse a lot of the existing infrastructure, and much of fsverity is based around it. So storing them in an xattrs causes a lot of churn in the interface. And the XFS side with special casing xattr indices also seems not exactly nice.
