the semantics in that the returned filename to use is now a kernel pointer rather than a user space pointer. This required changing the arguments to the CHECKALT*() macros some and changing the various system calls that used pathnames to use the kern_foo() functions that can accept kernel space filename pointers instead of calling the system call directly. - Use kern_open(), kern_access(), kern_msgctl(), kern_execve(), kern_mkfifo(), kern_mknod(), kern_statfs(), kern_fstatfs(), kern_setitimer(), kern_stat(), kern_lstat(), kern_fstat(), kern_utimes(), kern_pathconf(), and kern_unlink().
