Subject: vhost: move cuse only struct to cuse
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=adf97191b3e1495097658feaa6e2954a4aecfed5;p=dpdk.git

vhost: move cuse only struct to cuse

vhost cuse is now the last reference of the vhost_device_ctx struct;
move it there, and do a rename to "vhost_cuse_device_ctx", to make
it clear that it's "cuse only".
