From 343104308a33c4f1e23c8e841ede95e97b870842 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Tue, 23 Dec 2008 15:21:38 -0500 Subject: NFSv4: Fix up another delegation related race When we can update_open_stateid(), we need to be certain that we don't race with a delegation return. While we could do this by grabbing the nfs_client->cl_lock, a dedicated spin lock in the delegation structure will scale better.
