Subject: [PATCH v1 0/4] vduse: Reconnection support in vduse

Here is the reconnect support in vduse, 

The kernel will allocate pages for reconnection
userspace needs to use ioctl VDUSE_GET_RECONNECT_INFO to 
get the mmap related infomation and then map these pages
to userspace. 
The kernel and userspace will use these pages to sync
the reconnect information

Tested in vduse + dpdk test-pmd

Cindy Lu (4):
  vduse: Add function to get/free the pages for reconnection
  vduse: Add file operation for mmap
  vduse: Add new ioctl VDUSE_GET_RECONNECT_INFO
  vduse: update the vq_info in ioctl
