But I resend patch as attachment, is it invalid too ?
It doesn't have the mail mangling errors, but it has another one:
+ git apply --check --whitespace=error-all RESEND-net-next-v2-GRE-over-IPv6.patch
RESEND-net-next-v2-GRE-over-IPv6.patch:1999: new blank line at EOF.
+
fatal: 1 line adds whitespace errors.
