This breaks dumb string comparisons on these table lines in generic userspace device-mapper library code and leads to tables being reloaded repeatedly when nothing is actually meant to be changing. This patch corrects this by no longer changing the table line when discard passdown was disabled. We can still tell when discard passdown is overridden by looking for the message "Discard unsupported by data device (sdX): Disabling discard passdown." This automatic detection is also moved from the 'load' to the 'resume' so that it is re-evaluated should the properties of underlying devices change.

First off, if ACPI_STATE_D3 (equal to ACPI_STATE_D3_COLD) is passed to __acpi_bus_set_power() and the explicit_set flag is set for the D3cold state, the function will try to execute AML method called "_PS4", which doesn't exist. Fix this by adding a check to ensure that the name of the AML method to execute for transitions to ACPI_STATE_D3_COLD is correct in __acpi_bus_set_power(). Also make sure that the explicit_set flag for ACPI_STATE_D3_COLD will be set if _PS3 is present and modify acpi_power_transition() to avoid accessing power resources for ACPI_STATE_D3_COLD, because they don't exist. Second, if PCI_D3hot is passed to acpi_pci_set_power_state() as the target state, the function will request a transition to ACPI_STATE_D3_HOT instead of ACPI_STATE_D3. However, ACPI_STATE_D3_HOT is now only marked as supported if the _PR3 AML method is defined for the given device, which is rare. This causes problems to happen on systems where devices were successfully put into ACPI D3 by pci_set_power_state(PCI_D3hot) which doesn't work now. In particular, some unused graphics adapters are not turned off as a result. To fix this issue restore the old behavior of acpi_pci_set_power_state(), which is to request a transition to ACPI_STATE_D3 (equal to ACPI_STATE_D3_COLD) if either PCI_D3hot or PCI_D3cold is passed to it as the argument. This approach is not ideal, because generally power should not be removed from devices if PCI_D3hot is the target power state, but since this behavior is relied on, we have no choice but to restore it at the moment and spend more time on designing a better solution in the future.

As a result, the error message "NOHZ: local_softirq_pending 08" sometimes occurs during boot of a KVM guest when the network service is started and we are oom: ... Bringing up loopback interface: [ OK ] Bringing up interface eth0: Determining IP information for eth0...NOHZ: local_softirq_pending 08 done. [ OK ] ... Further, receive queue processing might get delayed indefinitely until some interrupt triggers: virtio_net expected napi to be run immediately. One way to cause do_softirq to be executed is by invoking local_bh_enable(). As __napi_schedule is normally called from bh or irq context, this seems to make sense: disable bh before __napi_schedule and enable afterwards. In fact it's a very complicated way of calling do_softirq(), and works since this function is only used when we are not in interrupt context. It's not hot at all, in any ideal scenario.

However, we don't update the config values for the new balloon size, resulting in the host showing outdated balloon values.

However, the host has to be told that the guest side of the connection is open to restore pre-suspend state. This wasn't noticed so far due to a bug in qemu that was fixed recently (which marked the guest-side connection as always open).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use del_timer_sync to remove timer before mddev_suspend finishes. We don't want a timer going off after an mddev_suspend is called. This is especially true with device-mapper, since it can call the destructor function immediately following a suspend. This results in the removal (kfree) of the structures upon which the timer depends - resulting in a very ugly panic. Therefore, we add a del_timer_sync to mddev_suspend to prevent this.

However raid10_resize isn't updating it at all! To update it correctly, we need to make sure it is a proper multiple of the chunksize taking various details of the layout in to account. This calculation is currently done in setup_conf. So split it out from there and call it from raid10_resize as well. Then set conf->dev_sectors properly. Signed-off-by: NeilBrown <neilb@suse.de>

Compounding this, gcc-4.7 can miscompile ipset such that even when the user specifies legitimate parameters the tool passes in an out-of-range size to the kernel. Fix from Jozsef Kadlecsik. 3) Users have reported that the netdev watchdog can trigger with pch_gbe devices, and it turns out this is happening because of races in the TX path of the driver leading to the transmitter hanging. Fix from Eric Dumazet, reported and tested by Andy Cress. 4) Novatel USB551L devices match the generic class entries for the cdc ethernet USB driver, but they don't work because they have generic descriptors and thus need FLAG_WWAN to function properly. Add the necessary ID table entry to fix this, from Dan Williams. 5) A recursive locking fix in the USBNET driver added a new problem, in that packet list traversal is now racy and we can thus access unlinked SKBs and crash. Avoid this situation by adding some extra state tracking, from Ming Lei. 6) The rtlwifi conversion to asynchronous firmware loading is racy, fix by reordering the probe procedure. From Larry Finger. Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=43187 7) Fix regressions with bluetooth keyboards by notifying userland properly when the security level changes, from Gustavo Padovan. 8) Bluetooth needs to make sure device connected events are emitted before other kinds of events, otherwise userspace will think there is no baseband link yet and therefore abort the sockets associated with that connection. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: netfilter: ipset: fix hash size checking in kernel ptp_pch: Add missing #include <linux/slab.h> pch_gbe: fix transmit races cdc_ether: add Novatel USB551L device IDs for FLAG_WWAN usbnet: fix skb traversing races during unlink(v2) Bluetooth: mgmt: Fix device_connected sending order Bluetooth: notify userspace of security level change rtlwifi: fix for race condition when firmware is cached
