NFSv4: Defer inode revalidation when setting up a delegation
Currently we force a synchronous call to __nfs_revalidate_inode() in nfs_inode_set_delegation(). This not only ensures that we cannot call nfs_inode_set_delegation from an asynchronous context, but it also slows down any call to open(). Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
