[PATCH v1] vhost: avoid large order allocations
A test case which generates memory pressure while performing guest administration
fails with vhost triggering "page allocation failure" and guest not starting up.
After some analysis we discovered the allocation order of vhost to be rensponsible
for this behaviour. Thus we suggest patch 1/1 which dynamically allocates the
required memory. Please see its description for details.
Thanks,

From: Dong Dong Chen <ddongch at cn.ibm.com>
Under memory pressure we observe load issues with module vhost_net, as the
vhost setup code will try to do an order 4 allocation for the device.
The likeliness of this issue to occur can be reduced when the statically
allocated variable "iov" in "struct vhost_virtq...
