/* 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.
