Linus Torvalds 6639c3ce7f fsverity updates for 6.3
Fix the longstanding implementation limitation that fsverity was only
 supported when the Merkle tree block size, filesystem block size, and
 PAGE_SIZE were all equal.  Specifically, add support for Merkle tree
 block sizes less than PAGE_SIZE, and make ext4 support fsverity on
 filesystems where the filesystem block size is less than PAGE_SIZE.
 
 Effectively, this means that fsverity can now be used on systems with
 non-4K pages, at least on ext4.  These changes have been tested using
 the verity group of xfstests, newly updated to cover the new code paths.
 
 Also update fs/verity/ to support verifying data from large folios.
 There's also a similar patch for fs/crypto/, to support decrypting data
 from large folios, which I'm including in this pull request to avoid a
 merge conflict between the fscrypt and fsverity branches.
 
 There will be a merge conflict in fs/buffer.c with some of the foliation
 work in the mm tree.  Please use the merge resolution from linux-next.
