如何在12.04上对上游12.10内核进行平分？

Question

我想在ubuntu主线内核上找到一个内核回归(来自内核-ppa/主线-内核Ubuntu)，在Qualal3.6.1和QUINTAL3.6.2之间。我建立在Mint 13玛雅(这是基于Ubuntu精确。我知道这不是百分之百的纯Ubuntu，但我认为在这种情况下，这种差异不应该影响“询问Ubuntu”中问题的相关性)：

为此，我尝试遵循内核/KernelBisection并发出以下命令(3445cb2e52e98dd2413bdc6bcccab475d3871dc1是由git二分bad返回的commit )：

git clone git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-stable
git clone git://kernel.ubuntu.com/ubuntu/kteam-tools.git
PATH=$PATH:/home/adam/tmp/kteam-tools/mainline-build
cd linux-stable
git remote add quantal git://kernel.ubuntu.com/ubuntu/ubuntu-quantal.git
git bisect start
git bisect good v3.6.1
git bisect bad v3.6.2
mainline-build-one 3445cb2e52e98dd2413bdc6bcccab475d3871dc1 quantal

最后一个命令返回：

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b new_branch_name

    mm: fix invalidate_complete_page2() lock ordering

    commit ec4d9f626d5908b6052c2973f37992f1db52e967 upstream.

    In fuzzing with trinity, lockdep protested "possible irq lock inversion
    dependency detected" when isolate_lru_page() reenabled interrupts while
    still holding the supposedly irq-safe tree_lock:

    invalidate_inode_pages2
      invalidate_complete_page2
        spin_lock_irq(&mapping->tree_lock)
        clear_page_mlock
          isolate_lru_page
            spin_unlock_irq(&zone->lru_lock)

    isolate_lru_page() is correct to enable interrupts unconditionally:
    invalidate_complete_page2() is incorrect to call clear_page_mlock() while
    holding tree_lock, which is supposed to nest inside lru_lock.

    Both truncate_complete_page() and invalidate_complete_page() call
    clear_page_mlock() before taking tree_lock to remove page from radix_tree.
     I guess invalidate_complete_page2() preferred to test PageDirty (again)
    under tree_lock before committing to the munlock; but since the page has
    already been unmapped, its state is already somewhat inconsistent, and no
    worse if clear_page_mlock() moved up.

我怀疑这与我为Quantal构建的内核的精确性有关。也许这条路径不支持这种跨版本的构建场景。或者，本教程遗漏了内核黑客明显的一些东西，我不知道。

更新：

我想我需要为devscripts安装dch，但是问题仍然存在；我已经更新了输出。

Answer 1

我更新了这里的操作：https://wiki.ubuntu.com/Kernel/KernelBisection#Bisecting_上游_内核_版本_至_单人_提交

现在它指向https://wiki.ubuntu.com/KernelTeam/GitKernelBuild，它比前面的指令工作得更好。

我仍然在努力使GitKernelBuild页面变得更好，但是它会引导您完成整个设置，而不是主线构建-1。

请让我知道这是否对你有用，如果还有什么可以改进的关于这些文件。
