From b7aa3d39385dc2d95899f9e379623fef446a2acd Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Thu, 6 Apr 2017 17:02:01 -0400 Subject: nbd: add a reconfigure netlink command We want to be able to reconnect dead connections to existing block devices, so add a reconfigure netlink command. We will also allow users to change their timeout on the fly, but everything else will require a disconnect and reconnect. You won't be able to add more connections either, simply replace dead connections with new more lively connections.
