Ensure that nfs_vm_page_mkwrite() waits for the page writeback to complete before the application is allowed to modify page contents. The main reason for wanting to do this in NFS is to ensure that the server doesn't get confused if we have to resend the RPC request due to a dropped/missed reply.

This is a cleanup patch. We don't need this reference anymore, because blocklayout pipes dentries now creates and destroys in per-net operations and on PipeFS mount/umount notification. Note that nfs4blocklayout_register_net() now returns 0 instead of -ENOENT in case of PipeFS superblock absence. This is ok, because blocklayout pipe dentry will be created on PipeFS mount event.

This patch subscribes blocklayout pipes to RPC pipefs notifications. Notifier is registering on blocklayout module load. This notifier callback is responsible for creation/destruction of PipeFS blocklayout pipe dentry. Note that no locking required in notifier callback because PipeFS superblock pointer is passed as an argument from it's creation or destruction routine and thus we can be sure about it's validity.

This patch implements blocklayout pipe creation and registration per each existent network namespace. This was achived by registering NFS per-net operations, responsible for blocklayout pipe allocation/register and unregister/destruction instead of initialization and destruction of static "bl_device_pipe" pipe (this one was removed). Note, than pointer to network blocklayout pipe is stored in per-net "nfs_net" structure, because allocating of one more per-net structure for blocklayout module looks redundant. This patch also changes dev_remove() function prototype (and all it's callers, where it' requied) by adding network namespace pointer parameter, which is used to discover proper blocklayout pipe for rpc_queue_upcall() call.

v2: 1) Added "nfs_idmap_init" and "nfs_idmap_quit" definitions for kernels built without CONFIG_NFS_V4 option set. This patch subscribes NFS clients to RPC pipefs notifications. Idmap notifier is registering on NFS module load. This notifier callback is responsible for creation/destruction of PipeFS idmap pipe dentry for NFS4 clients. Since ipdmap pipe is created in rpc client pipefs directory, we have make sure, that this directory has been created already. IOW RPC client notifier callback has been called already. To achive this, PipeFS notifier priorities has been introduced (RPC clients notifier priority is greater than NFS idmap one). But this approach gives another problem: unlink for RPC client directory will be called before NFS idmap pipe unlink on UMOUNT event and will fail, because directory is not empty. The solution, introduced in this patch, is to try to remove client directory once again after idmap pipe was unlinked. This looks like ugly hack, so probably it should be replaced in some more elegant way. Note that no locking required in notifier callback because PipeFS superblock pointer is passed as an argument from it's creation or destruction routine and thus we can be sure about it's validity.

This patch adds new net variable to nfs_client structure. This variable is set on NFS client creation and cheched during matching NFS client search. Initially current->nsproxy->net_ns is used as network namespace owner for new NFS client to create. This network namespace pointer is set during mount options parsing and thus can be passed from user-spave utils in future if will be necessary.

This patch looks late due to GSS AUTH patches sent already. But it fixes a flaw in RPC PipeFS pipes handling. I've added this patch in the series, because this series related to pipes. But it should be a part of previous series named "SUNPRC: cleanup PipeFS for network-namespace-aware users". Pipe dentry can be created and destroyed many times during pipe life cycle. This actually means, that we can't set pipe->ops to NULL in rpc_close_pipes() and use this variable as a flag, indicating, that pipe's dentry is unlinking. To follow this restriction, this patch replaces "pipe->ops = NULL" assignment and checks for NULL with "pipe->dentry = NULL" assignment and checks for NULL respectively. This patch also removes check for non-NULL pipe->ops (or pipe->dentry) in rpc_close_pipes() because it always non-NULL now.

This patch implements DNS resolver cache creation and registration for each alive network namespace context. This was done by registering NFS per-net operations, responsible for DNS cache allocation/register and unregister/destructioning instead of initialization and destruction of static "nfs_dns_resolve" cache detail (this one was removed). Pointer to network dns resolver cache is stored in new per-net "nfs_net" structure. This patch also changes nfs_dns_resolve_name() function prototype (and it's calls) by adding network pointer parameter, which is used to get proper DNS resolver cache pointer for do_cache_lookup_wait() call. Note: empty nfs_dns_resolver_init() and nfs_dns_resolver_destroy() functions will be used in next patch in the series.
