Date: Mon, 6 May 2013 16:12:43 -0700 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Trond Myklebust <Trond.Myklebust@...app.com> Subject: [ 084/104] NFSv4: Handle NFS4ERR_DELAY and NFS4ERR_GRACE in nfs4_open_delegation_recall 3.8-stable review patch. If anyone has any objections, please let me know. ------------------ From: Trond Myklebust <Trond.Myklebust@...app.com> commit 8b6cc4d6f841d31f72fe7478453759166d366274 upstream. A server shouldn't normally return NFS4ERR_GRACE if the client holds a delegation, since no conflicting lock reclaims can be granted, however the spec does not require the server to grant the open in this instance Signed-off-by: Trond Myklebust <Trond.Myklebust@...app.com> Signed-off-by: Greg Kroah-Hartman <gregkh@...uxfoundation.org> --- fs/nfs/nfs4proc.c | 6 ++++++ 1 file changed, 6 insertions(+) --- a/fs/nfs/nfs4proc.c +++ b/fs/nfs/nfs4proc.c @@ -1374,6 +1374,12 @@ int nfs4_open_delegation_recall(struct n case -ENOMEM: err = 0; goto out; + case -NFS4ERR_DELAY: + case -NFS4ERR_GRACE: + set_bit(NFS_DELEGATED_STATE, &state->flags); + ssleep(1); + err = -EAGAIN; + goto out; } err = nfs4_handle_exception(server, err, &exception); } while (exception.retry); -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
