From 8d39d801d64658d7d69e4754f287a71e9f9bbcb8 Mon Sep 17 00:00:00 2001 From: Miklos Szeredi Date: Thu, 30 Aug 2012 19:24:35 +0200 Subject: cuse: kill connection on initialization error Luca Risolia reported that a CUSE daemon will continue to run even if initialization of the emulated device failes for some reason (e.g. the device number is already registered by another driver). This patch disconnects the fuse device on error, which will make the userspace CUSE daemon exit, albeit without indication about what the problem was.
