It can't, I guess.  But maybe you could extract it from syzbot
information about the context of that patch?

Maybe tagging it with the git tree you fetched when getting it over git,
and mail from[1]+subject+message-id when getting it over email?

[1] processing of related headers to handle mailing lists and
retransmits is required, e.g. ressent-*, etc.  But this is relatively
easy to do as well.

A map to generate subject prefixes from key git trees or MLs could
enhance that even further, to get at least mainline:, *-next:, etc.
