7.4. EA Ondisk Format

The name can actually be binary data since it has a length field on disk

XFS kernel functions have been changed to handle binary names (used for future parent pointer EA's)

XFS EA's are stored in a variety of forms according to how big they are

Local or short form
- within the inode
Attribute-fork extents in either
- a filesystem leaf block
- btree form with node blocks and leaf blocks
Extent form
- the EA value can be in a remote filesystem block if it's large
