Isn't this you?

Yes. The patches are generated using git format-patch and sent by
git send-email. That's how it always created patches for me. I am not sure if
there is a config I can change to avoid having From:

We should be able to copy upto count bytes

Why?

Without this we end up doing

 +    struct kvm_get_htab_buf {
 +        struct kvm_get_htab_header header;
 +        /*
 +         * Older kernel required one extra byte.
 +         */
 +        unsigned long hpte[3];
 +    } hpte_buf;


even though we are only looking for one hpte entry.
