Wait a minute, this is actually wrong. You need to call vma_lock_anon_vma() / vma_unlock_anon_vma() to avoid the issue with vma->anon_vma == NULL. I'll fix it and integrate it into my next patch series, which I intend to send later today. (I am adding new code into validate_mm(), so that it's easier to have it in the same patch series to avoid merge conflicts) -- Michel "Walken" Lespinasse A program is never fully debugged until the last user dies. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
