If anyone has any objections, please let me know. ------------------ From: Michael Grzeschik [ Upstream commit 795f8eeca01d1c9ca3d9a450385b7745ace4e53a ] This patch is setting the client status to Disconnected, when the client is still in use. Otherwise a disconnected usb cable would run any use of the mount to faults.
