That email actually looks fine.

Yes, it has that

fro=
m

pattern, but it also has

Content-Transfer-Encoding: quoted-printable

so the recipient should be doing the right thing with that pattern.

The patch itself also has MIME encoding in it:

- cur_nr_pages =3D min(end_pfn - pfn, -(pfn | PAGE_SECTION_MASK));
+ cur_nr_pages =3D min(end_pfn - pfn,

so the patch wouldn't even apply unless the recipient did the proper
MIME decode of the message.

That's also why the non-raw message looks fine:

https://lore.kernel.org/linux-mm/20200228095819.10750-2-david@redhat.com/

because the raw message data has the proper encoding information.

In contrast, look at the email that Andrew sent me and that I complained about:

https://lore.kernel.org/linux-mm/20200329021719.MBKzW0xSl%25akpm@linux-foundation.org/

and notice how that *non-raw* email has that

Withou=
t

pattern in it. And when you look at the raw one:

https://lore.kernel.org/linux-mm/20200329021719.MBKzW0xSl%25akpm@linux-foundation.org/raw

it has no content transfer encoding line in the headers.
