This patch series will allow for the pivot_root syscall to be made optional. The first patch refactors the functions that are required by pivot_root so they can be accessed outside of fs/namespace.c. The second patch moves the pivot_root syscall to its own file. The third adds a Kconfig option and conditional compilation to the Makefile.
The pivot_root syscall is not needed on systems that do not use any intermediate filesystem. Allowing for pivot_root to be ommitted from the kernel will aid in the tinification efforts.
