Sorry for the second reply to the same mail - I expect this defintion to be in patch 7, where it logically belongs.. > +#define XFS_RMAP_BLOCK(mp) \ > (xfs_sb_version_hasfinobt(&((mp)->m_sb)) ? \ > XFS_FIBT_BLOCK(mp) + 1 : \ > XFS_IBT_BLOCK(mp) + 1) Is there any good reason for the variable offset for the rmap block. Yes, it saves one otherwise unused block per AG, but fixed offsets for metadata make a format much easier to understand. _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
