I think the "Reported-by: " line should continue to contain an e-mail,
since that way "git send-email" will automatically include a Cc: to
the mailing list address so that the syzbot page for the report will
contain a link to the page.

What *would* be useful would be a search box on the top-level
https://syzkaller.appspot.com where you could either enter an e-mail
address like:

	syzbot+726dc8c62c3536431ceb@xxxxxxxxxxxxxxxxxxxxxxxxx

or the syzbot report title e.g.:

       KCSAN: data-race in random_recv_done / virtio_read (3)

or just a function name:

	sys_quotactl_fd

The search box could just push the text to google.com with
"site:syzkaller.appspot.com", which should mostly do the right thing.

Also, it would also be nice if all of the URL links on the
syzkaller.appspot.com used the id form of the URL.  That is, to use

https://syzkaller.appspot.com/bug?extid=6c73bd34311ee489dbf5

instead of:

https://syzkaller.appspot.com/bug?id=32c54626e170a6b327ca2c8ae4c1aea666a8c20b

The extid form of the URL is shorter, and having a consistency so that
the primary URL is the extid would reduce confusion.  The web site
will need to continue to support the id form of the URL since there
are quite a few of those URL's in mailing list archives and git commit
descriptions.  

It also would be useful if there was a way to translate from the extid
hash to the id hash, so that it's possible to search for the extid and
id forms of the URL --- since the URL aliasing means that for a
developer trying to do code archeology and web searches, that we need
to search for both URL forms for past syzbot reports.  (But if we can
avoid the aliasing confusion moving forward, that would be **really**
nice.)
