Challenge accepted. This was a good thing for me to do because I found some opportunities to improve the XArray API. Changes since yesterday: - Added XA_NO_TAG - Added 'max' parameters to xa_get_entries() and xa_get_tagged() - Changed the order of the arguments of xa_get_entries() and xa_get_tagged() to match the radix tree equivalents You can see the patches on that (rebased) branch: xfs: Convert mru cache to XArray xfs: Convert xfs dquot to XArray xfs: Convert pag_ici_root to XArray xfs: Convert m_perag_tree to XArray or did you want me to send them by email?
