/* 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.
