刚才看到这篇文章http://www.xda-developers.com/android/googles-5-rumored-nexus-devices-may-not-be-what-you-think/
里面有这么几句:
If Android entirely skips the Linux 3.1, 3.2 and 3.3 kernels, several benefits await. The Linux 3.3 developmental kernel had several additions that incorporated Android into the heart of Linux. One of the biggest changes in the Linux 3.3 development cycle was the integration of key Android components, which bring the Android kernel into the Linux mainline.
我了解了一下,原因大概是这样。现在Linux 3.3内核开始将android一些驱动整合到主线去了,将来会将整个android驱动层面的东西全部纳入进Linux主线。
