selinux: fix style issues in security/selinux/ss/context.h As part of on ongoing effort to perform more automated testing and provide more tools for individual developers to validate their patches before submitting, we are trying to make our code "clang-format clean". My hope is that once we have fixed all of our style "quirks", developers will be able to run clang-format on their patches to help avoid silly formatting problems and ensure their changes fit in well with the rest of the SELinux kernel code.

selinux: hash context structure directly Always hashing the string representation is inefficient. Just hash the contents of the structure directly (using jhash). If the context is invalid (str & len are set), then hash the string as before, otherwise hash the structured data. Since the context hashing function is now faster (about 10 times), this patch decreases the overhead of security_transition_sid(), which is called from many hooks. The jhash function seemed as a good choice, since it is used as the default hashing algorithm in rhashtable.
