fsverity: hoist statx reporting of fs-verity flag (2026-10-04 19:47:47 +0200)

----------------------------------------------------------------

Patches from Andrey Albershteyn to prepare for XFS fsverity support:

- Report verification errors through fserror, instead of only through an unstructured log message and generic I/O error return

- Move the reporting of STATX_ATTR_VERITY into the VFS, so that each fsverity-capable filesystem doesn't need to do it. This also fixes a bug where btrfs didn't return STATX_ATTR_VERITY in attributes_mask

- Make the VFS prevent enabling DAX on fsverity files, so that it will be handled in a single place for ext4 and XFS

- Move ext4 and f2fs's code to read verity metadata from the pagecache into shared code, so that XFS will be able to use it too

- Export fsverity_ensure_verity_info() for XFS scrub to use

- Pass all-zeroes hash to ->write_merkle_tree_block() so that XFS will be able to implement an optimization for sparse files

----------------------------------------------------------------
