F13 has backported vhost_net driver from net-next, but it does not have
the bugfixes that were applied to it in 2.6.34. The fixes in question are:
17660f8 vhost: fix TUN=m VHOST_NET=y
5659338 vhost-net: switch to smp barriers
86e9424 vhost: logging thinko fix
73a99f0 vhost: initialize log eventfd context pointer
d6db3f5 vhost: fix get_user_pages_fast error handling
39286fa vhost-net: restart tx poll on sk_sndbuf full
1dace8c vhost: fix error path in vhost_net_set_backend
0e25557 vhost: fix interrupt mitigation with raw sockets
535297a vhost: fix error handling in vring ioctls
179b284 vhost-net: fix vq_memory_access_ok error checking
The patches fix serious issues in vhost-net driver.
Could these be cherry-picked for F13 kernel please?
The patches are non-intrusive and apply in F13 without changes.
