[PATCH 2/3] lockd: per-net NSM client creation and destruction helpers introduced

NSM RPC client can be required on NFSv3 umount, when child reaper is dying (and destroying it's mount namespace). It means, that current nsproxy is set to NULL already, but creation of RPC client requires UTS namespace for gaining hostname string. This patch introduces reference counted NFS RPC cli

[PATCH 1/3] lockd: use rpc client's cl_nodename for id encoding

Taking hostname from uts namespace if not safe, because this cuold be performind during umount operation on child reaper death. And in this case current->nsproxy is NULL already. Signed-off-by: Stanislav Kinsbursky Cc: --- fs/lockd/mon.c | 14 -- 1 files changed, 8 insertions(+),

[PATCH 0/3] lockd: use per-net refrence-counted NSM clients

This is a bug fix for https://bugzilla.redhat.com/show_bug.cgi?id=830862. The problem is that with NFSv4 mount in container (with separated mount namesapce) and active lock on it, dying child reaped of this container will try to umount NFS and doing this will try to create RPC client to send unmon

[PATCH] Xen backend support for paged out grant targets V4.

Since Xen-4.2, hvm domains may have portions of their memory paged out. When a foreign domain (such as dom0) attempts to map these frames, the map will initially fail. The hypervisor returns a suitable errno, and kicks an asynchronous page-in operation carried out by a helper. The foreign domain is
