>Description:
The rules for using the namecache are not clear, every file
system's rename vop will cache_purge different sets of vnodes
under different sets of conditions none of which is obviously
correct, we probably overzealously clear the cache in various
circumstances, and the whole thing shouldn't have its tendrils
in the file systems at all anyway.
>How-To-Repeat:
Code inspection.
>Fix:
Yes, please!
