Why not make LKML-Reference useful?

Why not make LKML-Reference useful?

[Lin Ming]

What's LKML-Reference in the kernel git log?
In my understanding, it's a link to the original discussion of the
patch on LKML, for example

LKML-Reference: http://marc.info/?l=linux-kernel&m=128445596126705&w=2

But I never see such a link in the LKML-Reference of the git log.

$cd linux-2.6
$git log | grep LKML-Reference

    LKML-Reference: <201008300127.o7U1RC6Z044051@www262.sakura.ne.jp>
    LKML-Reference: <20100913102541.20260.85700.stgit@ltc236.sdl.hitachi.co.jp>

    LKML-Reference: <1284159350-19841-2-git-send-email-venki@google.com>
    LKML-Reference: <new-submission>
......

Those LKML-Reference are really useless.

Why not put a link in LKML-Reference?

Thanks,

No they're not, those are the Message-IDs of the referenced headers
which can be used to search archives with.

Now, links OTOH *would* be useless on the long run as there's no single
entity maintaining LKML archives, so whatever entity you link to, you
become dependent on.  Having Message-IDs at least allows you to search
any available archive (provided it allows searching on Message-IDs).

The message id for the email sent to LKML.

Domains come and go (marc.theaimsgroup.com => marc.info => ?), message
id's are forever.

Also, you should be able to look up the message on your favorite
LKML-archive website or search engine using the message id.

Marc and Gmane allow search by Message-ID:

e.g.

http://marc.info/?i=20100913121903.GB22238@darkstar
