Oh, hm... You could take a mutex with trylock I suppose. That would be safe. Anyway, I just saw that you sent a v2 patch. When you send a v2 patch, then you *must* send a reply to the original thread. Greg has thousands and thousands of messages in his inbox and he applies patches in chronological order. So he will apply this one because it has not responses then get to the v2 patch and try to apply that one as well which will fail. regards, dan carpenter -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
