Masami - while looking at your set from last Friday, patch 1/5 fails to apply since the file being modified has the wrong line endings in the tree.
Oh, OK. is it CR/LF?
2/2 fixes that. (Obviously, the patch looks nonsensical since SMTP strips the added CR back out.)
Thanks for fixing!
1/2 adds you as a reviewer to the Socionext platforms. (This means that you will be cc:d on any future patches to these, and that I can use your Reviewed-by for 2/2.)
