Well it gets us back to the issue why we removed the lock. As Robin said before: If its global then we can have a huge number of tasks contending for the lock on startup of a process with a large number of ranks. The reason to go to mmap_sem was that it was placed in the mm_struct and so we would just have a couple of contentions per mm_struct. I'll be looking for some other way to do this. -- 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/
