[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,

[PATCH RFC V2 0/4] Adding tracepoints to vhost/net
Recent debugging on vhost net zerocopy shows the need of
tracepoints. So to help in vhost{net} debugging and performance
analyzing, the following series adding basic tracepoints to
vhost. Operations of both vhost and vhost_net were traced in current
implementation.
A top-like satistics displaying script were introduced to help the
troubleshooting:
vhost statistics
