I sent the full serie to Matthew Wilcox only, as he wanted to help re-sending the full serie. Then I saw that only 6 patches appeared in the linux-doc mailing list. I can try to send the three pending patches in different stages (for examp= le one patch every 4 or 5 hours) to avoid blocking my email. I hope. Or I can send the three pending patches only to the kernel-hardening mailing list and you re-send to all the people involved. Or any other solution you propose.
