+static inline struct xattr_handler *ocfs2_xattr_handler(int name_index)You seem to need the handler mostly for getting back to the prefix
+{
+ struct xattr_handler *handler = NULL;
+
+ if (name_index > 0 && name_index < OCFS2_XATTR_MAX)
+ handler = ocfs2_xattr_handler_map[name_index];
+
+ return handler;
+}
from the handler. This is a pretty clear indicator that you don't
want to use the xattr_handler splitting but deal with the whole
attr name. Take a look at the btrfs code after my recent xattr changes
on how to handle this more nicely.
Tao, Can you look into this?
