History
csjp bff7d924ba Axe Giant from vn_fullpath(9). The vnode -> pathname lookup should be 
filesystem agnostic. We are not touching any file system specific functions
in this code path. Since we have a cache lock, there is really no need to
keep Giant around here.

This eliminates Giant acquisitions for any syscall which is auditing pathnames.
