Bruce Fields" , Jeff Layton Cc: linux-nfs@vger.kernel.org Subject: [PATCH 28/32] nfsd4: properly type op_func callbacks Date: Tue, 9 May 2017 11:20:06 +0200 Message-Id: <20170509092010.30752-29-hch@lst.de> In-Reply-To: <20170509092010.30752-1-hch@lst.de> References: <20170509092010.30752-1-hch@lst.de> Sender: linux-nfs-owner@vger.kernel.org List-ID: Pass union nfsd4_op_u to the op_func callbacks instead of using unsafe function pointer casts. It also adds two missing structures to struct nfsd4_op.u to facilitate this.
