The mana_set_channels() function requires detaching the mana
driver and reattaching it with changed channel values.
During this operation if the system is low on memory, the reattach
might fail, causing the network device being down.
To avoid this we pre-allocate buffers at the beginning of set ope

Currently napi_disable() gets called during rxq and txq cleanup,
even before napi is enabled and hrtimer is initialized. It causes
kernel panic.

For primary VM Bus channels, primary_channel pointer is always NULL. This
pointer is valid only for the secondary channels. Also, rescind callback
is meant for primary channels only.
Fix NULL pointer dereference by retrieving the device_obj from the parent
for the primary ch
Rescind offer handling relies on rescind callbacks for some of the
resources cleanup, if they are registered. It does not unregister
vmbus device for the primary channel closure, when callback is
registered. Without it, next onoffer does not come, rescind flag

Fix a few issues in rescind handling in uio_hv_generic driver.
Patches are based on latest linux-next tip.
Steps to reproduce issue:
* Probe uio_hv_generic driver and create channels to use fcopy
* Disable the guest service on host and then Enable it.
or
* repeatedly do cat "/dev/uioX" on the devi
