提交 efb0c44 以后，为多用户扫描添加可选开关
|
|
建议不添加开关，刚看了下，全部扫一个用户的所有应用其实几十毫秒就能完成，没必要增加复杂性 |
看术哥怎么说吧，对于内核来说确实越小的开销越好 |
|
我也不建议加开关。之前 comment 里面的 Optional 指的是对开发者而言的，如果想做可以加上，不想做就不做；并非把这个选择权给用户，用户看到这个开关可能会很懵逼。 |
好的 |

我觉得直接在内核中直接遍历/data是否会导致部分机型在解析时如果遇到了加密或挂载状态有概率会导致内核死锁 |
|
因为它是一个动态目录，而不是像packages.list一样是一个静态文件 |

move to always kthreaded and mitigate sporadic deadlocks on ref tiann/KernelSU#2757 tiann/KernelSU#2759
Added filesystem type checks to prevent dangerous paths
|
这些fs magic是怎么选的 |
|
如果在 work queue 中处理会有一个问题：用户装完了管理器然后立即打开，如果此时 scan 还没结束，会显示“未安装”；因此之前都是阻塞处理的。 |
我们在选定管理器的时候，已经扫描了 |
有偶发性的概率，但是不高，会无缘无故突然在安装任意apk的过程中直接卡死 |

tiann/KernelSU#2759 also remove the prune thing, we can afford that since we are kthreaded
