/**
* fscrypt_is_nokey_name() - test whether a dentry is a no-key name
* @dentry: the dentry to check
*
* This returns true if the dentry is a no-key dentry. A no-key dentry is a
* dentry that was created in an encrypted directory that hasn't had its
* encryption key added yet. Such dentries may be either positive or negative.
*
* When a filesystem is asked to create a new filename in an encrypted directory
* and the new filename's dentry is a no-key dentry, it must fail the operation
* with ENOKEY. This includes ->create(), ->mkdir(), ->mknod(), ->symlink(),
* ->rename(), and ->link(). (However, ->rename() and ->link() are already
* handled by fscrypt_prepare_rename() and fscrypt_prepare_link().)
*
* This is necessary because creating a filename requires the directory's
* encryption key, but just checking for the key on the directory inode during
* the final filesystem operation doesn't guarantee that the key was available
* during the preceding dentry lookup. And the key must have already been
* available during the dentry lookup in order for it to have been checked
* whether the filename already exists in the directory and for the new file's
* dentry not to be invalidated due to it incorrectly having the no-key flag.
*
* Return: %true if the dentry is a no-key name
