2006-07-21[NET]: sun happymeal, little pci cleanupJiri Slaby
Use pci_register_driver instead of pci_module_init. Use PCI_DEVICE macro. Signed-off-by: Jiri Slaby <jirislaby@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-07-21[IrDA]: Use alloc_skb() in IrDA TX pathSamuel Ortiz
As pointed out by Christoph Hellwig, dev_alloc_skb() is not intended to be used for allocating TX sk_buff. The IrDA stack was exclusively calling dev_alloc_skb() on the TX path, and this patch fixes that. Signed-off-by: Samuel Ortiz <samuel@sortiz.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2006-07-21[PKT_SCHED] netem: Fix slab corruption with netem (2nd try)Guillaume Chazarain
CONFIG_DEBUG_SLAB found the following bug: netem_enqueue() in sch_netem.c gets a pointer inside a slab object: struct netem_skb_cb *cb = (struct netem_skb_cb *)skb->cb; But then, the slab object may be freed: skb = skb_unshare(skb, GFP_ATOMIC) cb is still pointing inside the freed skb, so here is a patch to initialize cb later, and make it clear that initializing it sooner is a bad idea.

2006-07-16[libata] ata_piix: Consolidate PCS register writingJeff Garzik
Prior to this patch, the driver would do this for each port: read 8-bit PCS write 8-bit PCS read 8-bit PCS write 8-bit PCS In the field, flaky behavior has been observed related to this register. In particular, these overzealous register writes can cause misdetection problems. Update to do the following once (not once per port) at boot: read 16-bit PCS if needs changing, write 16-bit PCS And thereafter, we only perform a 'read 16-bit PCS' per port. This should eliminate all PCS writes in many cases, and be more friendly in the cases where we do need to enable ports. Signed-off-by: Jeff Garzik <jeff@garzik.org>

2006-07-14[PATCH] remove set_wmb - arch removalSteven Rostedt
set_wmb should not be used in the kernel because it just confuses the code more and has no benefit. Since it is not currently used in the kernel this patch removes it so that new code does not include it. All archs define set_wmb(var, value) to do { var = value; wmb(); } while(0) except ia64 and sparc which use a mb() instead. But this is still moot since it is not used anyway. Hasn't been tested on any archs but x86 and x86_64 (and only compiled tested) Signed-off-by: Steven Rostedt <rostedt@goodmis.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-07-14[PATCH] Remove down_write() from taskstats code invoked on the exit() pathShailabh Nagar
In send_cpu_listeners(), which is called on the exit path, a down_write() was protecting operations like skb_clone() and genlmsg_unicast() that do GFP_KERNEL allocations. If the oom-killer decides to kill tasks to satisfy the allocations,the exit of those tasks could block on the same semphore. The down_write() was only needed to allow removal of invalid listeners from the listener list. The patch converts the down_write to a down_read and defers the removal to a separate critical region. This ensures that even if the oom-killer is called, no other task's exit is blocked as it can still acquire another down_read. Thanks to Andrew Morton & Herbert Xu for pointing out the oom related pitfalls, and to Chandra Seetharaman for suggesting this fix instead of using something more complex like RCU.

2006-07-14[PATCH] per-task delay accounting taskstats interface: control exit data ↵Shailabh Nagar
through cpumasks On systems with a large number of cpus, with even a modest rate of tasks exiting per cpu, the volume of taskstats data sent on thread exit can overflow a userspace listener's buffers. One approach to avoiding overflow is to allow listeners to get data for a limited and specific set of cpus. By scaling the number of listeners and/or the cpus they monitor, userspace can handle the statistical data overload more gracefully. In this patch, each listener registers to listen to a specific set of cpus by specifying a cpumask. The interest is recorded per-cpu. When a task exits on a cpu, its taskstats data is unicast to each listener interested in that cpu. Thanks to Andrew Morton for pointing out the various scalability and general concerns of previous attempts and for suggesting this design.

2006-07-14[PATCH] per-task delay accounting: avoid send without listenersShailabh Nagar
Don't send taskstats (per-pid or per-tgid) on thread exit when no one is listening for such data. Currently the taskstats interface allocates a structure, fills it in and calls netlink to send out per-pid and per-tgid stats regardless of whether a userspace listener for the data exists (netlink layer would check for that and avoid the multicast). As a result of this patch, the check for the no-listener case is performed early, avoiding the redundant allocation and filling up of the taskstats structures.

2006-07-14[PATCH] delay accounting taskstats interface send tgid onceShailabh Nagar
Send per-tgid data only once during exit of a thread group instead of once with each member thread exit. Currently, when a thread exits, besides its per-tid data, the per-tgid data of its thread group is also sent out, if its thread group is non-empty. The per-tgid data sent consists of the sum of per-tid stats for all *remaining* threads of the thread group. This patch modifies this sending in two ways: - the per-tgid data is sent only when the last thread of a thread group exits. This cuts down heavily on the overhead of sending/receiving per-tgid data, especially when other exploiters of the taskstats interface aren't interested in per-tgid stats - the semantics of the per-tgid data sent are changed. Instead of being the sum of per-tid data for remaining threads, the value now sent is the true total accumalated statistics for all threads that are/were part of the thread group. The patch also addresses a minor issue where failure of one accounting subsystem to fill in the taskstats structure was causing the send of taskstats to not be sent at all. The patch has been tested for stability and run cerberus for over 4 hours on an SMP.
