* [PATCH] knfsd: convert sk_reserved to atomic_tGreg Banks2006-10-021-7/+5
| | | | | | | | | | | Convert the svc_sock->sk_reserved variable from an int protected by svc_serv->sv_lock, to an atomic. This reduces (by 1) the number of places we need to take the (effectively global) svc_serv->sv_lock.

* [PATCH] knfsd: use new lock for svc_sock deferred listGreg Banks2006-10-021-6/+6
| | | | | | | | | | | Protect the svc_sock->sk_deferred list with a new lock svc_sock->sk_defer_lock instead of svc_serv->sv_lock. Using the more fine-grained lock reduces the number of places we need to take the svc_serv lock.

* [PATCH] knfsd: move tempsock aging to a timerGreg Banks2006-10-022-26/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Following are 11 patches from Greg Banks which combine to make knfsd more Numa-aware. They reduce hitting on 'global' data structures, and create some data-structures that can be node-local. knfsd threads are bound to a particular node, and the thread to handle a new request is chosen from the threads that are attach to the node that received the interrupt. The distribution of threads across nodes can be controlled by a new file in the 'nfsd' filesystem, though the default approach of an even spread is probably fine for most sites. Some (old) numbers that show the efficacy of these patches: N == number of NICs == number of CPUs == nmber of clients. Number of NUMA nodes == N/2 N Throughput, MiB/s CPU usage, % (max=N*100) Before After Before After --- ------ ---- ----- ----- 4 312 435 350 228 6 500 656 501 418 8 562 804 690 589 This patch: Move the aging of RPC/TCP connection sockets from the main svc_recv() loop to a timer which uses a mark-and-sweep algorithm every 6 minutes. This reduces the amount of work that needs to be done in the main RPC loop and the length of time we need to hold the (effectively global) svc_serv->sv_lock.

* [PATCH] knfsd: allow sockets to be passed to nfsd via 'portlist'NeilBrown2006-10-021-4/+45
| | | | | | | | | | | | Userspace should create and bind a socket (but not connectted) and write the 'fd' to portlist. This will cause the nfs server to listen on that socket. To close a socket, the name of the socket - as read from 'portlist' can be written to 'portlist' with a preceding '-'.

* [PATCH] knfsd: define new nfsdfs file: portlist - contains list of portsNeilBrown2006-10-021-0/+40

Default when TCP enabled will be ipv4 udp 0.0.0.0 2049 ipv4 tcp 0.0.0.0 2049 Later, the list of ports will be settable. 'portlist' chosen rather than 'ports', to avoid unnecessary confusion with non-mainline patches which created 'ports' with different semantics.

* [PATCH] Kprobes: Make kprobe modules more portableAnanth N Mavinakayanahalli2006-10-021-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In an effort to make kprobe modules more portable, here is a patch that: o Introduces the "symbol_name" field to struct kprobe. The symbol->address resolution now happens in the kernel in an architecture agnostic manner. 64-bit powerpc users no longer have to specify the ".symbols" o Introduces the "offset" field to struct kprobe to allow a user to specify an offset into a symbol. o The legacy mechanism of specifying the kprobe.addr is still supported. However, if both the kprobe.addr and kprobe.symbol_name are specified, probe registration fails with an -EINVAL. o The symbol resolution code uses kallsyms_lookup_name(). So CONFIG_KPROBES now depends on CONFIG_KALLSYMS o Apparantly kprobe modules were the only legitimate out-of-tree user of the kallsyms_lookup_name() EXPORT. Now that the symbol resolution happens in-kernel, remove the EXPORT as suggested by Christoph Hellwig o Modify tcp_probe.c that uses the kprobe interface so as to make it work on multiple platforms (in its earlier form, the code wouldn't work, say, on powerpc) Signed-off-by: Ananth N Mavinakayanahalli <ananth@in.ibm.com> Signed-off-by: Prasanna S Panchamukhi <prasanna@in.ibm.com> Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] const struct tty_operationsJeff Dike2006-10-022-2/+2
| | | | | | | | | | | | | | | | | | | | | | | As part of an SMP cleanliness pass over UML, I consted a bunch of structures in order to not have to document their locking. One of these structures was a struct tty_operations. In order to const it in UML without introducing compiler complaints, the declaration of tty_set_operations needs to be changed, and then all of its callers need to be fixed. This patch declares all struct tty_operations in the tree as const. In all cases, they are static and used only as input to tty_set_operations. As an extra check, I ran an i386 allyesconfig build which produced no extra warnings. 53 drivers are affected. I checked the history of a bunch of them, and in most cases, there have been only a handful of maintenance changes in the last six months. serial_core.c was the busiest one that I looked at.

| | | | | | | | | | | Currently if the sender is sending small messages, it can cause a receiver to run out of receive buffer space even when the advertised receive window is still open and results in packet drops and retransmissions.
