Further, the size of the structure that is filled in is determined by the version of the ioctl being called, not the xfs_fs_geometry() function. Hence the caller already knows the size of the structure being used, and hence does not need xfs_fs_geometry() to tell it that information. So I don't think this change is necessary.
