[PULL v3 44/85] vhost-user: Skip unnecessary duplicated VHOST_USER_SET_LOG_BASE requests
Posted by Michael S. Tsirkin 5 months, 4 weeks ago
From: BillXiang <xiangwencheng@dayudpu.com>

The VHOST_USER_SET_LOG_BASE requests should be categorized into
non-vring specific messages, and should be sent only once.
If send more than once, dpdk will munmap old log_addr which may has been used and cause segmentation fault.
