Looks right, but checkpatch.pl has some complaints about the spaces:
please fix those. Maybe you started off with tabs, and gmail turned
them into spaces. gmail is an outstandingly excellent mailer (;)
but unhelpful on patches. See Documentation/email-clients.txt or
Documentation/zh_CN/email-clients.txt. Maybe "git send-email" will
get around it for you.
Thanks,
