+Severity   : enhancement
+Jira       : LU-6050
+Description: control OST-index in IDIF via  ROCOMPAT flag.
+Details    : Introduce new flag OBD_ROCOMPAT_IDX_IN_IDIF that is stored in the
+            last_rcvd file. For new formatted OST device, it will be auto set;
+            for the case of upgrading from old OST device, you can enable it
+            via the lproc interface osd-ldiskfs.index_in_idif. With such flag
+            enabled, for new created OST-object, its IDIF-in-LMA will contain
+            the OST-index; for the existing OST-object, the OSD will convert
+            old format IDIF as new format IDIF with OST-index stored in the
+            LMA EA when accessing such OST-object or via OI scrub. Once such
+            flag is enabled, it cannot be reverted back, so the system cannot
+            be downgraded to the orignal incompatible version.
