+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.
