? There is a/security subdirectory In the android kernel that stores security-related modules, including LSM, SELinux, smack, and other modules. Google did not remove LSM from the android kernel. This provides favorable conditions for compiling smack.So how to compile smack? Let's take a look at the files in/security/smack.

The processing after data entry has always been very important. The poor dean of the Anhui Examination Institute missed the college entrance examination data (to tell the truth, this mistake is really not easy ...)
