Hi David, Inline functions xfs_dir2_dataptr_to_byte and xfs_dir2_byte_to_dataptr are not using their 1st argument. gcc is able to optimize that out. I still want to delete these parameters, as they serve no useful purpose and by removing them I can make gcc to notice some additional unused variables in the callers of these inlines, and warn me about that. There is no object code size difference from this change. Compile tested only. Signed-off-by: Denys Vlasenko -- vda
