Message-Id: <1367933964-1564-77-git-send-email-luis.henriques@canonical.com> Date: Tue, 7 May 2013 14:38:42 +0100 From: Luis Henriques <luis.henriques@...onical.com> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org, kernel-team@...ts.ubuntu.com Cc: Trond Myklebust <Trond.Myklebust@...app.com>, Luis Henriques <luis.henriques@...onical.com> Subject: [PATCH 076/118] NFSv4: Handle NFS4ERR_DELAY and NFS4ERR_GRACE in nfs4_open_delegation_recall 3.5.7.12 -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> [ luis: adjust context ] Signed-off-by: Luis Henriques <luis.henriques@...onical.com> --- fs/nfs/nfs4proc.c | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/fs/nfs/nfs4proc.c b/fs/nfs/nfs4proc.c index b96aa12..480918e 100644 --- a/fs/nfs/nfs4proc.c +++ b/fs/nfs/nfs4proc.c @@ -1381,6 +1381,12 @@ int nfs4_open_delegation_recall(struct nfs_open_context *ctx, struct nfs4_state 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); -- 1.8.1.2 -- 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/
