Bruce Fields" , linux-kernel@vger.kernel.org Subject: [PATCH v2 07/17] nfsd: don't keep a pointer to the lease in nfs4_file Date: Thu, 4 Sep 2014 08:38:33 -0400 Message-Id: <1409834323-7171-8-git-send-email-jlayton@primarydata.com> In-Reply-To: <1409834323-7171-1-git-send-email-jlayton@primarydata.com> References: <1409834323-7171-1-git-send-email-jlayton@primarydata.com> Sender: linux-nfs-owner@vger.kernel.org List-ID: Now that we don't need to pass in an actual lease pointer to vfs_setlease on unlock, we can stop tracking a pointer to the lease in the nfs4_file. Switch all of the places that check the fi_lease to check fi_deleg_file instead. We always set that at the same time so it will have the same semantics. Cc: J.
