We check the pointers together but at least one of them could be invalid due to failed allocation. Since we cannot continue if either of the two allocations has failed, exit early by freeing them both.

This is needed for determining the reason for failure when a softdog timeout occurs. We use softdog to watch for critical application failures and at the minimum a snapshot of the system would help to determine the cause. In such a scenario the application could fail but there isn't a softlockup as such, hence the detect softlockup feature does not help. The patch adds a module parameter soft_panic which when set to 1 causes softdog to invoke panic instead of reboot when the softdog timer expires. By invoking panic we execute kdump if it is configured and the vmcore generated by kdump should provide atleast a minimal idea of the reason for failure.

While testing the performance of different receive interrupt coalescing settings on a single stream TCP benchmark, I noticed two very different results. With rx-usecs=50, most of the time a connection would hit 8280 Mbps but once in a while it would hit 9330 Mbps. It turns out we are only applying the interrupt coalescing settings to the first queue and whenever the rx hash would direct us onto that queue we ran faster. With this patch applied and rx-usecs=50, I get 9330 Mbps consistently. Signed-off-by: NAnton Blanchard <anton@samba.org> Acked-by: NDivy Le Ray <divy@chelsio.com> Signed-off-by: NDavid S.

In commit 95a0f10c ("drbd: store in-core bitmap little endian, regardless of architecture") drbd had made the sane choice to use little-endian bitmap functions everywhere. However, it used the horrible old functions names from <asm-generic/bitops/le.h>, that were never really meant to be exported. In the meantime, things got cleaned up, and in commit c4945b9e ("asm-generic: rename generic little-endian bitops functions") we renamed the LE bitops to something sane, exactly so that they could be used in random code without people gouging their eyes out when seeing the crazy jumble of letters that were the old internal names. As a result the drbd thing merged cleanly (commit 8d49a775: "Merge branch 'for-2.6.39/drivers' of git://git.kernel.dk/linux-2.6-block"), since there was no data conflict - but the end result obviously doesn't actually compile.

Acer WMI hotkey event's result include current device status, just need sync the status to killswitch after acer-wmi driver receive hotkey event but not always poll device status. This is good for performance. But, if use EC raw mode, Acer BIOS will not emit wmi event and leave EC to control device status. So, still startup polling job when doesn't detect WMI event GUID or user choice to use ec_raw_mode. Tested on Acer TravelMate 8572 notebook.

Acer BIOS keeps devices state when system reboot, but reset to default device states (Wlan on, Bluetooth off, wwan on) if system cold boot. That means BIOS's initial state is not always real persistence. So, removed rfkill_init_sw_state because it sets initial state to persistence then replicate to other new killswitch when rfkill-input enabled. After removed it, acer-wmi set initial soft-block state after rfkill register, and doesn't allow set_block until rfkill initial finished.
