Say I have the following situation where there is a file called foo in the
/tmp directory. How can I given the inode for the file 'foo' get the inode
for the directory, /tmp. This is within kernel space.

I know nothing about kernel space, but I would say you can't do it.
Think of hard links (and a file having multiple links): there is no
unique 1:1 relationship between a file (or its inode) and the parent
directory (or its inode). A file can have any N >= 0 parents.
