There are no interruptible waits for asynchronous RPC tasks, so we don't need to wrap calls to rpc_run_task() with an rpc_clnt_sigmask/rpc_clnt_unsigmask pair. Instead we can wrap the wait_for_completion_interruptible() in nfs_direct_wait(). This means that we completely optimise away sigmask setting for the case of non-blocking aio/dio.

Now that each NFS mount point caches its own nlm_host structure, it can be passed to nlmclnt_proc() for each lock request. By pinning an nlm_host for each mount point, we trade the overhead of looking up or creating a fresh nlm_host struct during every NLM procedure call for a little extra memory. We also restrict the nlmclnt_proc symbol to limit the use of this call to in-tree modules. Note that nlm_lookup_host() (just removed from the client's per-request NLM processing) could also trigger an nlm_host garbage collection. Now client-side nlm_host garbage collection occurs only during NFS mount processing. Since the NFS client now holds a reference on these nlm_host structures, they wouldn't have been affected by garbage collection anyway. Given that nlm_lookup_host() reorders the global nlm_host chain after every successful lookup, and that a garbage collection could be triggered during the call, we've removed a significant amount of per-NLM-request CPU processing overhead. Sidebar: there are only a few remaining references to the internals of NFS inodes in the client-side NLM code. The only references I found are related to extracting or comparing the inode's file handle via NFS_FH(). One is in nlmclnt_grant(); the other is in nlmclnt_setlockargs().

Cache an appropriate nlm_host structure in the NFS client's mount point metadata for later use. Note that there is no need to set NFS_MOUNT_NONLM in the error case -- if nfs_start_lockd() returns a non-zero value, its callers ensure that the mount request fails outright.

We would like to remove the per-lock-operation nlm_lookup_host() call from nlmclnt_proc(). The new architecture pins an nlm_host structure to each NFS client superblock that has the "lock" mount option set. The NFS client passes in the pinned nlm_host structure during each call to nlmclnt_proc(). NFS client unmount processing "puts" the nlm_host so it can be garbage- collected later. This patch introduces externally callable NLM functions that handle mount-time nlm_host set up and tear-down.

Clean up: have the set up routines explicitly pass the strings to be used for the transport name and NETID.

Refactor the logic to parse incoming text-based IP addresses. Use the in4_pton() function instead of the older in_aton(), following the lead of the in-kernel CIFS client. Later we'll add IPv6 address parsing using the matching in6_pton() function. For now we can't allow IPv6 address parsing: we must expand the size of the address storage fields in the nfs_parsed_mount_options struct before we can parse and store IPv6 addresses.

Change the addr field in the nfs_clone_mount structure to store a "struct sockaddr *" to support non-IPv4 addresses in the NFS client. Note this is mostly a cosmetic change, and does not actually allow referrals using IPv6 addresses. The existing referral code assumes that the server returns a string that represents an IPv4 address. This code needs to support hostnames and IPv6 addresses as well as IPv4 addresses, thus it will need to be reorganized completely (to handle DNS resolution in user space).
