freebsd-skq/sys/kern/kern_cap.c
rwatson 6de51f4efd Merge from POSIX.1e Capabilities development tree:
o Reorder and synchronize #include's, including moving "opt_cap.h" to
  above system includes.
o Introduce #ifdef'd kern.security.capabilities sysctl tree, including
  kern.security.capabilities.enabled, which defaults to 0.

The rest of the file remains stubs for the time being.
