From 7b81119b1d3904cf00ec29140e8bc5d86a12902f Mon Sep 17 00:00:00 2001 From: Eric Sandeen Date: Mon, 4 Mar 2013 16:35:42 -0600 Subject: btrfs-progs: Issue warnings if ioctls fail in sigint handlers The two sigint handlers issue ioctls to clean up, but if they fail, noone would know. I'm not sure there is any other error handling to be done at this point, but a notification seems wise.
