In preparation for doing wrap around mappings for ring buffers cleanup
vmbus_open() function:
- check that ring sizes are PAGE_SIZE aligned (they are for all in-kernel
drivers now);
- kfree(open_info) on error only after we kzalloc() it (not an issue as it
is valid to call kfree(NULL);
- rename
With wrap around mappings in place we can always provide drivers with
direct links to packets on the ring buffer, even when they wrap around.
Do the required updates to get_next_pkt_raw()/put_pkt_raw()

K. Y.,
I'd like to accompany your netvsc performance improvement work by making
in-place consumption of VMBus packets always possible. Currently we forbid
it when a packet 'wraps around' the ring so we can't provide a single
pointer to it.
The idea if this series is dead simple: let's make a sing
Make it possible to always use a single memcpy() or to provide a direct
link to a packet on the ring buffer by creating virtual mapping for two
copies of the ring buffer with vmap(). Utilize currently empty
hv_ringbuffer_cleanup() to do the unmap.
While on it, replace sizeof(struct hv_ring_buffer)

Hello,
The intent of this patch is not to solve the corruptions for sure, but only to
avoid the concerned MEs/small-MDs LNet structs to be quite frequently impacted
due to their high allocation/free rate. This may also possibly help to save
cycles due to high usage and contention when using a ge

This script helps to create bonding network devices based on synthetic NIC
(the virtual network adapter usually provided by Hyper-V) and the matching
VF NIC (SRIOV virtual function). So the synthetic NIC and VF NIC can
function as one network device, and fail over to the synthetic NIC if VF is
