+ * Lustre wire protocol definitions.
+ *
+ * ALL structs passing over the wire should be declared here. Structs
+ * that are used in interfaces with userspace should go in lustre_user.h.
+ *
+ * All structs being declared here should be built from simple fixed-size
+ * types (__u8, __u16, __u32, __u64) or be built from other types or
+ * structs also declared in this file. Similarly, all flags and magic
+ * values in those structs should also be declared here. This ensures
+ * that the Lustre wire protocol is not influenced by external dependencies.
+ *
+ * The only other acceptable items in this file are VERY SIMPLE accessor
+ * functions to avoid callers grubbing inside the structures. Nothing that
+ * depends on external functions or definitions should be in here.
+ *
+ * Structs must be properly aligned to put 64-bit values on an 8-byte
+ * boundary. Any structs being added here must also be added to
+ * utils/wirecheck.c and "make newwiretest" run to regenerate the
+ * utils/wiretest.c sources. This allows us to verify that wire structs
+ * have the proper alignment/size on all architectures.
+ *
+ * DO NOT CHANGE any of the structs, flags, values declared here and used
+ * in released Lustre versions. Some structs may have padding fields that
+ * can be used. Some structs might allow addition at the end (verify this
+ * in the code to ensure that new/old clients that see this larger struct
+ * do not fail, otherwise you need to implement protocol compatibility).

- * Lustre wire protocol definitions.
- *
- * ALL structs passing over the wire should be declared here. Structs
- * that are used in interfaces with userspace should go in lustre_user.h.
- *
- * All structs being declared here should be built from simple fixed-size
- * types (__u8, __u16, __u32, __u64) or be built from other types or
- * structs also declared in this file. Similarly, all flags and magic
- * values in those structs should also be declared here. This ensures
- * that the Lustre wire protocol is not influenced by external dependencies.
- *
- * The only other acceptable items in this file are VERY SIMPLE accessor
- * functions to avoid callers grubbing inside the structures. Nothing that
- * depends on external functions or definitions should be in here.
- *
- * Structs must be properly aligned to put 64-bit values on an 8-byte
- * boundary. Any structs being added here must also be added to
- * utils/wirecheck.c and "make newwiretest" run to regenerate the
- * utils/wiretest.c sources. This allows us to verify that wire structs
- * have the proper alignment/size on all architectures.
- *
- * DO NOT CHANGE any of the structs, flags, values declared here and used
- * in released Lustre versions. Some structs may have padding fields that
- * can be used. Some structs might allow addition at the end (verify this
- * in the code to ensure that new/old clients that see this larger struct
- * do not fail, otherwise you need to implement protocol compatibility).
