+/* NOTE: Rules for message additions
+ * 1) Each instance of a message is _better_ left with a unique message ID, even
+ * if the message format is the same. Reasoning is that, if the message
+ * format needs to change in one instance, the other instances are not
+ * impacted or the new change does not change the ID of the instance being
+ * modified.
+ * 2) Addition of a message,
+ * - Should increment the GLFS_NUM_MESSAGES
+ * - Append to the list of messages defined, towards the end
+ * - Retain macro naming as glfs_msg_X (for redability across developers)
+ * NOTE: Rules for message format modifications
+ * 3) Check acorss the code if the message ID macro in question is reused
+ * anywhere. If reused then then the modifications should ensure correctness
+ * everywhere, or needs a new message ID as (1) above was not adhered to. If
+ * not used anywhere, proceed with the required modification.
+ * NOTE: Rules for message deletion
+ * 4) Check (3) and if used anywhere else, then cannot be deleted. If not used
+ * anywhere, then can be deleted, but will leave a hole by design, as
+ * addition rules specify modification to the end of the list and not filling
+ * holes.
