Hi David, xfs_bmap_add_free and xfs_btree_read_bufl functions use some of their parameters only in some cases (e.g. if DEBUG is defined, or on non-Linux OS :) This patch removes these parameters using #define hack which makes them "disappear" without the need of uglifying every callsite with #ifdefs.
