Subject: [PATCH 2/4] fscrypt: Export fscrypt_d_ops
Date: Thu, 14 Mar 2019 18:15:57 +0100	[thread overview]
Message-ID: <20190314171559.27584-3-richard@nod.at> (raw)
In-Reply-To: <20190314171559.27584-1-richard@nod.at>

If a filesystem manages dentry operations itself it might want to
re-use fscrypt_d_ops.
