I can't make heads or tails of the VOP_REMOVE() rules for freeing
a_cnp.
The man page doesn't say anything about having to free cnp.
ufs_remove() doesn't bother.
nfs_remove() always frees it.
And the unlink() system call seems to expect the cnp to be freed
by the VOP_REMOVE() function.
Typically the rule for freeing a struct componentname in a VOP
routine is 'free it if you return an error, otherwise only free
it if the SAVESTART flag is not set in cn_flags'.
I would appreciate it if a VFS guru could look at this junk and
tell me whos right.
