This was confusing becuase it should have been [PATCH 4/4 v2]. These days I think the prefered way is to just resend the whole series as a new thread. Greg doesn't use patchwork, but these rules especially apply for subsystems which use patchwork. People say that patchwork gets confused when people use the --in-reply-to option and I guess it's hard to apply individual patches in patchwork? Anyway, just always start a new thread and resend everything. Send a reply to the original thread to say "Don't apply this one, it has sleeping in atomic bugs", otherwise it might get applied by mistake. regards, dan carpenter
