/**
+ * Different FID Format
+ * http://arch.lustre.org/index.php?title=Interoperability_fids_zfs#NEW.0
+ *
+ * FID:
+ * File IDentifier generated by client from range allocated by the seq service.
+ * First 0x400 sequences [2^33, 2^33 + 0x400] are reserved for system use. Note
+ * that on ldiskfs MDTs that IGIF FIDs can use inode numbers starting at 12,
+ * but this is in the IGIF SEQ rangeand does not conflict with assigned FIDs.
+ *
+ * IGIF:
+ * Inode and Generation In FID, a surrogate FID used to globally identify an
+ * existing object on OLD formatted MDT file system. This would only be used on
+ * MDT0 in a DNE filesystem, because there are not expected to be any OLD
+ * formatted DNE filesystems. Belongs to a sequence in [12, 2^32 - 1] range,
+ * where sequence number is inode number, and inode generation is used as OID.
+ * NOTE: This assumes no more than 2^32-1 inodes exist in the MDT filesystem,
+ * which is the maximum possible for an ldiskfs backend. NOTE: This assumes
+ * that the reserved ext3/ext4/ldiskfs inode numbers [0-11] are never visible
+ * to clients, which has always been true.
+ *
+ * IDIF:
+ * Object ID in FID, a surrogate FID used to globally identify an existing
+ * object on OLD formatted OST file system. Belongs to a sequence in
+ * [2^32, 2^33 - 1]. Sequence number is calculated as:
+ * 1 << 32 | (ost_index << 16) | ((objid >> 32) & 0xffff)
+ * that is, SEQ consists of 16-bit OST index, and higher 16 bits of object ID.
+ * The generation of unique SEQ values per OST allows the IDIF FIDs to be
+ * identified in the FLD correctly. The OID field is calculated as:
+ * objid & 0xffffffff
+ * that is, it consists of lower 32 bits of object ID. NOTE This assumes that
+ * no more than 2^48-1 objects have ever been created on an OST, and that no
+ * more than 65535 OSTs are in use. Both are very reasonable assumptions (can
+ * uniquely map all objects on an OST that created 1M objects per second for 9
+ * years, or combinations thereof).
+ *
+ * OST_MDT0:
+ * Surrogate FID used to identify an existing object on OLD formatted OST
+ * filesystem. Belongs to the reserved sequence 0, and is used internally prior
+ * to the introduction of FID-on-OST, at which point IDIF will be used to
+ * identify objects as residing on a specific OST.
+ *
+ * LLOG:
+ * For Lustre Log objects the object sequence 1 is used. This is compatible with
+ * both OLD and NEW.1 namespaces, as this SEQ number is in the ext3/ldiskfs
+ * reserved inode range and does not conflict with IGIF sequence numbers.
+ *
+ * ECHO:
+ * For testing OST IO performance the object sequence 2 is used. This is
+ * compatible with both OLD and NEW.1 namespaces, as this SEQ number is in the
+ * ext3/ldiskfs reserved inode range and does not conflict with IGIF sequence
+ * numbers.
+ *
+ * OST_MDT1 .. OST_MAX:
+ * For testing with multiple MDTs the object sequence 3 through 9 is used,
+ * allowing direct mapping of MDTs 1 through 7 respectively, for a total of 8
+ * MDTs including OST_MDT0. This matches the legacy CMD project "group"
+ * mappings. However, this SEQ range is only for testing prior to any production
+ * DNE release, as the objects in this range conflict across all OSTs, as the
+ * OST index is not part of the FID.
+ *
+ *
+ * For compatibility with existing OLD OST network protocol structures, the FID
+ * must map onto the o_id and o_gr in a manner that ensures existing objects are
+ * identified consistently for IO, as well as onto the lock namespace to ensure
+ * both IDIFs map onto the same objects for IO as well as resources in the DLM.
+ *
+ * DLM OLD OBIF/IDIF:
+ * resource[] = {o_id, o_seq, 0, 0}; // o_seq == 0 for production releases
+ *
+ * DLM NEW.1 FID (this is the same for both the MDT and OST):
+ * resource[] = {SEQ, OID, VER, HASH};
+ *
+ * Note that for mapping IDIF values to DLM resource names the o_id may be
+ * larger than the 2^33 reserved sequence numbers for IDIF, so it is possible
+ * for the o_id numbers to overlap FID SEQ numbers in the resource. However, in
+ * all production releases the OLD o_seq field is always zero, and all valid FID
+ * OID values are non-zero, so the lock resources will not collide.
+ *
+ * For objects within the IDIF range, group extraction (non-CMD) will be:
+ * o_id = (fid->f_seq & 0x7fff) << 16 | fid->f_oid;
+ * o_seq = 0; // formerly group number
+ */
+
+/**
* Note that reserved SEQ numbers below 12 will conflict with ldiskfs
* inodes in the IGIF namespace, so these reserved SEQ numbers can be
* used for other purposes and not risk collisions with existing inodes.
