[PATCH 3/4] xen/manage: Guard against user-space initiated poweroff and XenBus.
...p making
a duplicate call to kernel_power_off. There is no locking
there so we walk in the same steps as what ''poweroff''
has been doing.
The code in kernel/reboot.c has a mutex guarding against multiple
''poweroff'' operations. But not against the kernel ''orderly_poweroff''.
As such, lets detect this so that we don''t invoke orderly_poweroff
if the user had initiated a poweroff.
This is code by changing the ''shutting_down'' to an atomic and
having a reboot notifier. If the ''shutting_down'' is set to anything
but SH...

[PATCH 0000/0046] Staging: hv: Driver cleanup
Further cleanup of the hv drivers.
1) Cleanup reference counting.
2) Handle all block devices using the storvsc driver. I have modified
the implementation here based on Christoph's feedback on my earlier
implementation.
3) Fix bugs.
4) Accomodate some host side scsi emulation bugs.
5) In case of scsi errors off-line the device.
This patch-set further reduces the size of
