parentposix acls: Remove duplicate xattr name definitions (diff)
vfs: Distinguish between full xattr names and proper prefixes
Add an additional "name" field to struct xattr_handler. When the name is set, the handler matches attributes with exactly that name. When the prefix is set instead, the handler matches attributes with the given prefix and with a non-empty suffix. This patch should avoid bugs like the one fixed in commit c361016a in the future.
