From: Huawei Xie Date: Fri, 6 Mar 2015 10:39:18 +0000 (+0800) Subject: vhost: fix file descriptors naming X-Git-Tag: spdx-start~9480 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=64ab9717914f22e8b7a4842fb997c9587acd5191;p=dpdk.git vhost: fix file descriptors naming Previous vhost implementation wrongly name kickfd as callfd and callfd as kickfd. It is functional correct, but causes confusion. Exchange kickfd and callfd to avoid confusion.
