Most offset macro mess is used in xfs_stats_format() only, and we can simply get the right offsets using offsetof(), instead of several macros to mark the offsets inside __xfsstats structure. Replace all XFSSTAT_END_* macros by a single helper macro to get the right offset into __xfsstats, and use this helper in xfs_stats_format() directly. The quota stats code, still looks a bit cleaner when using XFSSTAT_* macros, so, this patch also defines XFSSTAT_START_XQMSTAT and XFSSTAT_END_XQMSTAT locally to that code. This also should prevent offset mistakes when updates are done into __xfsstats. Signed-off-by: Carlos Maiolino <cmaiolino@redhat.com> Reviewed-by: Darrick J.
