Subject: Re: [PATCH 00/26] Address Space Isolation (ASI) 2024

Well, off to a good start...

REFLECT MODE:
    The To: and Cc: headers will be fully populated, but the only
    address given to the mail server for actual delivery will be
    Brendan Jackman <jackmanb@...gle.com>

    Addresses in To: and Cc: headers will NOT receive this series.

Apparently gmail is too clever for this and sent my mail out anyway.
So, some corrections, more probably to come on monday.

Yes, this is an RFC, definitely not a PATCH. Sorry for the bogus
subject...
