I see, then we want one more LSM hook for clearing the hash table 
after returing from vfs_*().

foo() {
	error = security_path_foo(); /* save result in the hash table */
	error = vfs_foo(); /* fetch from the hash table in security_inode_*() */
	security_path_clear(); /* clear the hash table */
}

Is it acceptable?

Regards,
